btrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data()
In that function, we round down the start position and round up the
ending position.
But during the calculation of @len, we use "round_up(start + len,
sectorsize)", which is the rounded up end position, not the rounded up
length.
Which results a much larger length, and later we are still using
"start + len", which is completely incorrect.
Fix it by declaring a local @aligned_start and @aligned_len and use them
instead. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: validate orphan slot during inode read
Patch series "ocfs2: validate active orphan slots during inode read".
OCFS2 trusts active ordinary and append-DIO orphan slots read from dinodes.
A corrupted slot can therefore index osb_orphan_wipes or the slot-local
system-inode cache outside their allocations before the corruption is
reported.
Patch 1 validates the ordinary orphan slot used by inode wipe processing.
Patch 2 validates the append-DIO orphan slot used by DIO completion and
orphan recovery. Both checks reject corrupt metadata at the existing inode
validation boundary.
This patch (of 2):
[BUG]
A corrupted dinode with OCFS2_ORPHANED_FL can carry an
i_orphaned_slot outside the mounted filesystem slot range.
ocfs2_wipe_inode() uses it to index osb_orphan_wipes before looking
up the orphan directory, causing an out-of-bounds memory access.

dinode validation, before the inode reaches orphan wipe processing. |

ksmbd: fix slab-out-of-bounds read in ksmbd_alloc_user()
ksmbd_alloc_user() copies resp->hash_sz bytes out of the mountd IPC
login response with
user->passkey_sz = resp->hash_sz;
user->passkey = kmalloc(resp->hash_sz, KSMBD_DEFAULT_GFP);
if (user->passkey)
memcpy(user->passkey, resp->hash, resp->hash_sz);
resp->hash_sz is a __u16 supplied by the response, but resp->hash[] is
only KSMBD_REQ_MAX_HASH_SZ bytes. A malformed or malicious login
response can set hash_sz well beyond that (up to 65535), so the memcpy()
reads past the end of the response object. ipc_validate_msg() does not
bound hash_sz, so reject any response whose hash_sz exceeds the on-stack
hash[] buffer before allocating and copying.

| In the Linux kernel, the following vulnerability has been resolved:
net: qlcnic: validate unified ROM sections before loading
The unified ROM parser reads directory, product, and data-descriptor fields
from the firmware file. Existing validation forms table and data ends with
unchecked additions and multiplications. Malformed values can wrap before
they are compared with the firmware size. The parser also dereferences
typed pointers at firmware-controlled offsets.
Valid descriptor extents alone are insufficient for the consumers. The
loader reads a fixed-size bootloader regardless of its declared size, the
version parser assumes a 17-byte tail, and a partial final firmware word is
read as a full u64. A truncated image can therefore make the driver read
beyond the firmware allocation during validation or loading.
Replace the pointer-returning parser with bounded range helpers. Validate
table entry sizes, descriptor indices, section ranges, the fixed
bootloader load length, and the version tail before exposing any section.
Read all file fields with unaligned little-endian accessors and assemble a
partial final word from only the bytes that remain. Apply the same range
checks to the legacy image before reading its fixed fields. |

LoongArch: BPF: Refactor jump offset calculation in tail call
The old macro-based jmp_offset calculation derives the jump distance
from a stale prior-pass code stride, which can lead to wrong branch
offsets and soft lockups under extra JIT passes.
Fix this by calculating the offset directly on the absolute target:
"ctx->offset[insn + 1] - ctx->idx".
To avoid a false 16-bit range check abort during size estimation, add
a "ctx->image == NULL" guard to inject a safe dummy offset. |

drm/amdgpu: reject oversized IBs with per-ring packet limits
On GFX rings, amdgpu_cs_p2_ib() passed user-supplied ib_bytes through
to ib->length_dw without a limit, while ring_emit_ib() encodes length
into packet fields. Oversized values can corrupt adjacent control bits
and destabilize command submission.
Add a per-ring IB packet size limit helper and reject command
submissions exceeding the corresponding dword limit before IB
allocation. Use the documented 20-bit limit for GFX/compute/SDMA/VPE,
and apply the MM fallback limit for other ring types.

ipvs: revalidate ihl to prevent out-of-bounds access
While the outer IP header is already pulled into the skb head,
we must be careful and revalidate the embedded headers after
reading them from the skb frags to prevent out-of-bounds
access.
One such place reported by Sashiko is ip_vs_nat_icmp() where
local process can change the ihl field and after
skb_ensure_writable() we can see larger value which is a
problem for the ip_send_check(cih) calls.
Add check to drop the packet if the ihl field is changed. |

soc: aspeed: lpc-snoop: Fix usercopy overflow in snoop_file_read
put_fifo_with_discard() acts as both producer and consumer on the kfifo:
it calls kfifo_skip() (advances out) and kfifo_put() (advances in) from
the IRQ handler without synchronizing with snoop_file_read(), which also
consumes via kfifo_to_user(). On SMP systems this concurrent access can
leave (in - out) larger than the ring buffer, so __kfifo_to_user()'s clamp
to (in - out) is ineffective and kfifo_copy_to_user() can attempt a
copy_to_user() past the kmalloc-2k backing store:

btrfs: lzo: reject inline extents without valid headers

</TASK>
[CAUSE]
For an inline lzo compressed file extent, there should always be one lzo
header, recording the total length of the compressed data, followed by
one segment header, recording the compressed lzo payload.
But if a crafted inline lzo compressed file extent contains only an lzo
header, without the segment header or payload, lzo_decompress() will
still try to read the segment header, causing a read beyond the item
boundary.
Furthermore if the inline lzo compressed file extent is the first item
of the leaf, it will be at the extent buffer boundary. The above
out-of-boundary read will go beyond the extent buffer boundary,
triggering the above KASAN report.
[FIX]
Validate the total length of the inlined lzo compressed file extent, to
make sure there is at least one LZO header and one segment header, and a
non-zero payload.

ocfs2: validate fast symlink target during inode read
ocfs2_validate_inode_block() already rejects several inconsistent
self-contained dinodes before they are exposed to the rest of the
filesystem. Fast symlinks need the same treatment.
A zero-cluster symlink is treated as a fast symlink and later read through
page_get_link() and ocfs2_fast_symlink_read_folio(). That path uses
strnlen() on the inline payload and then copies len + 1 bytes into the
folio. If a corrupt dinode stores an i_size that does not fit the inline
area or omits the terminating NUL at i_size, that copy reads past the end
of the inode block buffer.
Reject zero-cluster symlink dinodes whose i_size exceeds the inline
fast-symlink capacity or whose inline payload is not NUL-terminated
exactly at i_size when the inode block is validated. This keeps malformed
fast symlinks from reaching the read path.

bnxt: fix head underflow on XDP head-grow
The xdp.py test test_xdp_native_adjst_head_grow_data crashes when run on
a bnxt machine (and also crashes in NIPA).
It seems that the bug is an underflow in bnxt_rx_multi_page_skb, which
builds the skb head:
napi_build_skb(data_ptr - bp->rx_offset, rxr->rx_page_size);
The problem with this expression is that in page mode, rx_offset is:
bp->rx_offset = NET_IP_ALIGN + XDP_PACKET_HEADROOM;
Which evaluates (at least on x86_64) to 258.
The test test_xdp_native_adjst_head_grow_data tests a case where the
head is adjusted by -256.
When this test runs, data_ptr is shifted to frag_start + 2 (where
frag_start = page_address(page) + offset).
Then, bnxt_rx_multi_page_skb is invoked and the napi_build_skb
expression subtracts 258, landing at an address before frag_start. This
could be either the previous fragment or the previous physical page when
the offset is < 256 (e.g. if the fragment started at offset 0).
When the skb is freed, the page pool fragment reference is dropped on
either the wrong page or the wrong frag of the right page. In either
case, the corrupted reference count can lead to the page being
prematurely recycled while still in use. Once (incorrectly) recycled, it
can be handed out again and on driver teardown this would result in a
double free.
The commit under fixes updated this code to handle the case where the
native page size is >= 64k, but it unintentionally broke the head grow
case.
To fix this, add an offset field to struct bnxt_sw_rx_bd, mirroring the
existing offset field in struct bnxt_sw_rx_agg_bd. Populate it on
allocation and preserve it on reuse.
In bnxt_rx_multi_page_skb, use the newly added offset field to compute
the fragment start and pass that to napi_build_skb. Adjust the layout
with skb_reserve.
There are two cases, the non-adjustment case and the adjustment case.
In both cases, the skb is built at page_address(page) + offset to
account for the case where the native page size >= 64K and skb_reserve
is called with data_ptr - (page_address(page) + offset). That
difference equals bp->rx_offset when data_ptr was not moved, or
bp->rx_offset + xdp_adjust when XDP adjusted the head.
Re-running the failing test with this commit applied causes the test to
run successfully to completion.
The other rx_skb_func implementations don't have this issue. |

wifi: mac80211: validate extension-frame layout before RX
Extension frames only have the extension header at the regular 802.11
header offset. The generic RX path can still reach helpers and interface
dispatch code that read regular header address fields before unsupported
extension subtypes are dropped.
mac80211 currently only handles S1G beacon extension frames. Drop other
extension subtypes before they can reach regular-header RX processing.
For S1G beacons, linearize the SKB with the management-frame path and
require the fixed S1G beacon header, including optional fixed fields
indicated by frame control, before generic RX dispatch.
Route S1G beacons through the station/default-link RX path without
regular-header station lookup. Avoid regular-header address reads in the
mac80211 RX paths that process S1G extension beacons, including
accept-frame, duplicate-detection, address-copy, and MLO
address-translation paths.
Also make ieee80211_get_bssid() length-safe before returning the S1G
source-address pointer. |

s390/zcrypt: Fix buffer over-read in cca_cipher2protkey
Add validation of both the actual key buffer size and token length
fields in all the cca_check_sec*token() functions. Additionally check
in cca_gencipherkey() for possible underflow with returned key size.
The CCA token structures contain user-controlled len fields that
were used in operations without proper validation against both the
actual buffer size and minimum token structure size. An attacker
could set this field larger than the actual buffer size, leading to
reading beyond buffer boundaries. This may result in a kernel crash or
exposure of memory via sending this as part of a request down to the
crypto card. Also an attacker could have used a very small len value
and thus enforce a buffer under-run which may produce similar effects
as a over-read.
So now a key must
- key buf length must be at least sizeof the token struct
- the key len field inside the token must fit into the range of
sizeof key token struct ... key buf length |

drm/amdkfd: clamp v9 CRIU control stack checkpoint copy to BO size
CRIU checkpoint copies the MQD control stack using cp_hqd_cntl_stack_size
from hardware without bounding it to the allocated BO region. If the HW
field is larger than the queue's control stack allocation, memcpy reads
past the BO into adjacent GTT memory and can leak kernel data to userspace.
Store the page-aligned control stack BO size in mqd_manager and clamp
checkpoint copies and reported checkpoint sizes to
min(cp_hqd_cntl_stack_size, mm->ctl_stack_size). Apply the same bound
for multi-XCC v9.4.3 checkpoint layout.

sched_ext: Don't warn on core-sched forced idle in put_prev_task_scx()
put_prev_task_scx() warns when a runnable task drops to a lower sched_class
without SCX_OPS_ENQ_LAST, on the assumption that balance_one() would have
kept it running. Core scheduling breaks that: a forced-idle SMT sibling
reschedules through the core_pick fast path in pick_next_task(), which skips
pick_task_scx() and thus balance_one(), so a runnable task can drop to idle
with ENQ_LAST unset.
Gate the warning on sched_cpu_cookie_match(): a cookie mismatch means core
scheduling forced the idle, while a match (or core scheduling off) still
catches a genuine missing-ENQ_LAST drop. |

net/mlx5: Fix MCIA register buffer overflow on 32 dword reads
The MCIA register can return up to 32 dwords (128 bytes) when the device
advertises the mcia_32dwords capability, but struct
mlx5_ifc_mcia_reg_bits only defines dword_0..11, leaving room for just
12 dwords (48 bytes) of data.
mlx5_query_mcia() clamps the read size to mlx5_mcia_max_bytes() and then
memcpy()s that many bytes out of the register, potentially reading past
the end of the 'out' buffer. On kernels built with FORTIFY_SOURCE this
is caught as a buffer overflow while reading the module EEPROM via
ethtool:
detected buffer overflow in memcpy

drm/i915/bios: range check LFP Data Block panel_type2
While the panel_type from LFP Data Block is range checked, panel_type2
is not. Add a few helpers for range checking, and use them to not only
check panel_type2, but also improve clarity and correctness in the panel
type selection.
Discovered using AI-assisted static analysis confirmed by Intel Product
Security.
v2:
- Fix commit message typo (Michał)
- Add is_panel_type_pnp() (Ville)
