| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: avoid out-of-bounds read for empty PREQ elements
ieee80211_mesh_preq_size_ok() derives the location of the PREQ bottom
fields before checking whether the element contains even the fixed
header. ieee80211_mesh_hwmp_preq_get_bottom() reads the flags byte to
account for the optional Address Extension field. Consequently, an
empty PREQ element causes a one-byte read beyond its declared payload.
Move the helper call after both size checks, so the bottom fields are
only accessed when they are present. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: p54: require a full exp_if record in PDR_INTERFACE_LIST
The PDR_INTERFACE_LIST loop only checks that the record start is within
the entry before reading an entire struct exp_if from it. A truncated
trailing record makes the if_id/variant reads cross the entry boundary
into the heap beyond the EEPROM buffer (verified with a KASAN
reproducer of the loop). The variant also feeds the synth front-end
selection, so this is not only a leak.
Advance only while a full record still fits in the entry. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: rmi_smbus - fix out-of-bounds read in rmi_smb_write_block()
When chunking writes into SMBus blocks in rmi_smb_write_block(), the
loop calculates block_len using the original total length (len) instead
of the remaining length (cur_len).
If len is greater than 32 bytes (SMB_MAX_COUNT), block_len remains 32
for every iteration, even on the final partial chunk where fewer than 32
bytes remain. This causes smb_block_write() to read 32 bytes from the
advanced data buffer pointer, reading past the end of the input buffer.
Fix this by calculating block_len using cur_len and advancing the buffer
and address pointers by block_len. |

| An out-of-bounds read vulnerability in FileMaker Server for Linux allowed an attacker uploading a specially crafted image file to a container field to disclose process memory during thumbnail generation in FileMaker WebDirect. This vulnerability is addressed in FileMaker Server version 26.0.3. |
| A vulnerability was detected in vgmstream up to r2117. Affected by this vulnerability is the function ps_find_padding of the file src/coding/psx_decoder.c of the component VAG File Handler. Performing a manipulation results in out-of-bounds read. The attack is possible to be carried out remotely. The patch is named 4b8316652a30d40f99ad43310bed273fd1f8a7a3. It is suggested to install a patch to address this issue. |
| A flaw has been found in NASA cFS up to 7.0.1. This issue affects the function CFE_FS_ParseInputFileNameEx of the file cfe/modules/fs/fsw/src/cfe_fs_api.c. This manipulation causes out-of-bounds read. Remote exploitation of the attack is possible. The pull request to fix this issue awaits acceptance. |
| Mooncake transfer engine before 0.3.12 contains an out-of-bounds read vulnerability in the readString function of include/common.h that allows unauthenticated attackers to crash the service by sending a zero-length handshake frame. Attackers can connect to the handshake port listening on all interfaces and send an eight-byte frame to terminate the hosting process, such as an SGLang inference server. |
| Ghidra versions 9.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries containing strings or constant byte stores that end in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output. |
| A flaw was found in tnef. An attacker can exploit this vulnerability by providing a specially crafted file containing uncompressed Rich Text Format (RTF) data. Because the application fails to properly validate input buffer boundaries before copying data in get_rtf_data_from_buf(), reading beyond the allocated memory occurs. This flaw can cause the application to crash, leading to a Denial of Service (DoS), or leak sensitive memory contents into extracted output files. |
| The JavaScript preprocessing (Duktape) engine on Zabbix server has a vulnerability where a limited administrator is able to read raw heap data potentially resulting in leaked data from other running preprocessors not available to said administrator. |
| An out-of-bounds read in libXi's XI2 enter/leave/focus cookie conversion in libXi before 1.8.4 could be used by malicious X server to crash an attached X client. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel: validate version TLV value lengths
btintel_parse_version_tlv() verifies that a complete TLV is present in
the response, but it does not ensure that the value is long enough for
the specific TLV type. A short value can therefore cause an
out-of-bounds read through get_unaligned_le16(), get_unaligned_le32(),
or memcpy().
Reject values shorter than the minimum required by each known TLV type.
Also reject responses that do not contain the Command Complete Status
field. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio_console: do not free control-out buffers on remove
__send_control_msg() publishes &portdev->cpkt as the control-out
virtqueue cookie. remove_vqs() walks every virtqueue and passes leftover
cookies to free_buf(), which treats them as struct port_buffer and
reads sgpages.
If a control message is still on c_ovq when the device is unbound,
free_buf() reads past the ports_device object.
KASAN reported slab-out-of-bounds in free_buf():
free_buf
remove_vqs
virtcons_remove
unbind_store
The object was the ports_device allocated in virtcons_probe().
Drain c_ovq without freeing. The packet lives in portdev and is released
with it. |
| In the Linux kernel, the following vulnerability has been resolved:
vhost/vdpa: reject VRING_NUM larger than device max
vhost_vring_set_num() accepts any non-zero power-of-two queue size that
fits in 16 bits. vhost-vdpa then passes that value to set_vq_num()
without comparing it with get_vq_num_max().
A process with access to /dev/vhost-vdpa-* can therefore configure a
queue larger than the device advertises. With vdpa_sim, the worker can
walk descriptors beyond the mapped descriptor ring. KASAN reports a
16-byte out-of-bounds read, corresponding to one vring_desc, in the
vringh IOTLB path:
BUG: KASAN: out-of-bounds in _copy_from_iter
Read of size 16
copy_from_iotlb
copydesc_iotlb
vringh_getdesc_iotlb
vdpasim_net_work
Cache get_vq_num_max() immediately after reset. Some backends derive
it from writable queue-size state, so querying it after SET_NUM may
return the current size instead of the device capability. Invalidate
the cached value before reset so a failed reset leaves SET_NUM
disabled.
For VHOST_SET_VRING_NUM, copy the complete vring state once and use
the same index and size for validation, vq->num, and set_vq_num().
This ensures that validation and use operate on the same copied values. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: fix tcp stream corruption with large pages
rds_message_map_pages() assigns PAGE_SIZE bytes to every
scatterlist entry, even when total_len ends in a partial page. The RDS
congestion map is defined as 8192 bytes, so on systems with PAGE_SIZE
greater than 8192 the scatterlist maps bytes beyond the end of the
congestion map. RDS-TCP transmits the SG contents according to those
lengths, so the extra bytes become part of the TCP RDS stream and are
interpreted as subsequent RDS message headers, corrupting the stream.
Limit the final scatterlist mapping to the number of bytes remaining.
This has no effect on systems with a 4K page size and allows RDS-TCP to
be used on systems with 16K and larger page sizes.
The RDS selftest, which previously hung on 16K pages, now passes. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usbusx2y: fix in04_last array size mismatch with in04_buf
The in04_last array in struct usx2ydev is declared as char[24], but
in04_buf is allocated as sizeof(struct us428_ctls) which is 21 bytes.
In i_usx2y_in04_int(), when ctl_snapshot_last == -2 (initialization
path):
memcpy(usx2y->in04_last, usx2y->in04_buf, sizeof(usx2y->in04_last));
This copies 24 bytes from a 21-byte slab allocation, reading 3 bytes
past the end of the source object.
Introduce a USX2Y_IN04_SIZE constant defined as sizeof(struct
us428_ctls) and use it consistently for the in04_last array, the
in04_buf allocation, the URB transfer length, and the comparison loop,
replacing the bare 24 and 21 literals throughout. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Keep the entry count when the histogram stats allocation fails
print_entries() uses n_entries both as the number of sort entries and as
its own return value, so the -ENOMEM it stores when the stats allocation
fails overwrites the count that the cleanup still needs:
n_entries = tracing_map_sort_entries(map, ...);
if (n_entries < 0)
return n_entries;
...
if (!stats) {
n_entries = -ENOMEM;
goto out;
}
...
out:
tracing_map_destroy_sort_entries(sort_entries, n_entries);
tracing_map_destroy_sort_entries() takes an unsigned int and loops up to
it, so -ENOMEM arrives as 4294967284. It walks an array of at most
map->max_elts pointers and calls destroy_sort_entry(), which dereferences
and frees, on whatever lies past the end.
Reading the hist file of a trigger with a .percent value, with that
allocation forced to fail:
BUG: KASAN: vmalloc-out-of-bounds in tracing_map_destroy_sort_entries+0xa0/0xb0
Read of size 8 at addr ffffc90000045000 by task init/1
tracing_map_destroy_sort_entries+0xa0/0xb0
hist_show+0x6f7/0x1df0
seq_read_iter+0x2b8/0x1190
vfs_read+0x176/0xa40
The buggy address belongs to a 4-page vmalloc region starting at
ffffc90000041000 allocated at tracing_map_sort_entries+0x5c/0xd50
A few pages further the fault is fatal. The registers at the oops confirm
the bound: the loop's end pointer less the array start, over the pointer
size, is 4294967284.
Return the error in a separate variable and leave n_entries holding the
count, the way tracing_map_sort_entries() does on its own error path.
The stats block is only entered for a value carrying .percent or .graph,
which __create_val_field() has rejected since v6.3, so this cannot be
reached in mainline as it stands. It becomes reachable again with
"tracing: hist: let values keep the percent and graph modifiers", so it
should be applied first. |
