| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()'
All error handling paths lead to 'out' where many resources are freed.
Do it as well here instead of a direct return, otherwise 'log', 'ra' and
'log->one_page_buf' (at least) will leak. |
| In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix an Oops in pnfs_mark_request_commit() when doing O_DIRECT
Fix an Oopsable condition in pnfs_mark_request_commit() when we're
putting a set of writes on the commit list to reschedule them after a
failed pNFS attempt. |
| In the Linux kernel, the following vulnerability has been resolved:
nfs: fix acl memory leak of posix_acl_create()
When looking into another nfs xfstests report, I found acl and
default_acl in nfs3_proc_create() and nfs3_proc_mknod() error
paths are possibly leaked. Fix them in advance. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: gadget: Bail from dwc3_gadget_exit() if dwc->gadget is NULL
There exists a possible scenario in which dwc3_gadget_init() can fail:
during during host -> peripheral mode switch in dwc3_set_mode(), and
a pending gadget driver fails to bind. Then, if the DRD undergoes
another mode switch from peripheral->host the resulting
dwc3_gadget_exit() will attempt to reference an invalid and dangling
dwc->gadget pointer as well as call dma_free_coherent() on unmapped
DMA pointers.
The exact scenario can be reproduced as follows:
- Start DWC3 in peripheral mode
- Configure ConfigFS gadget with FunctionFS instance (or use g_ffs)
- Run FunctionFS userspace application (open EPs, write descriptors, etc)
- Bind gadget driver to DWC3's UDC
- Switch DWC3 to host mode
=> dwc3_gadget_exit() is called. usb_del_gadget() will put the
ConfigFS driver instance on the gadget_driver_pending_list
- Stop FunctionFS application (closes the ep files)
- Switch DWC3 to peripheral mode
=> dwc3_gadget_init() fails as usb_add_gadget() calls
check_pending_gadget_drivers() and attempts to rebind the UDC
to the ConfigFS gadget but fails with -19 (-ENODEV) because the
FFS instance is not in FFS_ACTIVE state (userspace has not
re-opened and written the descriptors yet, i.e. desc_ready!=0).
- Switch DWC3 back to host mode
=> dwc3_gadget_exit() is called again, but this time dwc->gadget
is invalid.
Although it can be argued that userspace should take responsibility
for ensuring that the FunctionFS application be ready prior to
allowing the composite driver bind to the UDC, failure to do so
should not result in a panic from the kernel driver.
Fix this by setting dwc->gadget to NULL in the failure path of
dwc3_gadget_init() and add a check to dwc3_gadget_exit() to bail out
unless the gadget pointer is valid. |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: check for null after calling kmemdup
kmemdup can return a null pointer so need to check for it, otherwise
the null key will be dereferenced later in tipc_crypto_key_xmit as
can be seen in the trace [1].

| In the Linux kernel, the following vulnerability has been resolved:
media: i2c/tw9906: Fix potential memory leak in tw9906_probe()
In one of the error paths in tw9906_probe(), the memory allocated in
v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that
by calling v4l2_ctrl_handler_free() on the handler in that error path. |

| In the Linux kernel, the following vulnerability has been resolved:
NFC: pn533: bound the UART receive buffer
pn532_receive_buf() appends every incoming byte to dev->recv_skb and
only resets the buffer after pn532_uart_rx_is_frame() recognizes a
complete frame. A continuous stream of bytes without a valid PN532 frame
header therefore keeps growing the skb until skb_put_u8() hits the tail
limit.
Drop the accumulated partial frame once the fixed receive buffer is full
so malformed UART traffic cannot grow the skb past
PN532_UART_SKB_BUFF_LEN. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix memory leak on failure path
cfg80211_inform_bss_frame() may return NULL on failure. In that case,
the allocated buffer 'buf' is not freed and the function returns early,
leading to potential memory leak.
Fix this by ensuring that 'buf' is freed on both success and failure paths. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: Clear reconnect pending bit
When canceling the reconnect worker, care must be taken to reset the
reconnect-pending bit. If the reconnect worker has not yet been
scheduled before it is canceled, the reconnect-pending bit will stay
on forever. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: No shortcut out of RDS_CONN_ERROR
RDS connections carry a state "rds_conn_path::cp_state"
and transitions from one state to another and are conditional
upon an expected state: "rds_conn_path_transition."
There is one exception to this conditionality, which is
"RDS_CONN_ERROR" that can be enforced by "rds_conn_path_drop"
regardless of what state the condition is currently in.
But as soon as a connection enters state "RDS_CONN_ERROR",
the connection handling code expects it to go through the
shutdown-path.
The RDS/TCP multipath changes added a shortcut out of
"RDS_CONN_ERROR" straight back to "RDS_CONN_CONNECTING"
via "rds_tcp_accept_one_path" (e.g. after "rds_tcp_state_change").
A subsequent "rds_tcp_reset_callbacks" can then transition
the state to "RDS_CONN_RESETTING" with a shutdown-worker queued.
That'll trip up "rds_conn_init_shutdown", which was
never adjusted to handle "RDS_CONN_RESETTING" and subsequently
drops the connection with the dreaded "DR_INV_CONN_STATE",
which leaves "RDS_SHUTDOWN_WORK_QUEUED" on forever.
So we do two things here:
a) Don't shortcut "RDS_CONN_ERROR", but take the longer
path through the shutdown code.
b) Add "RDS_CONN_RESETTING" to the expected states in
"rds_conn_init_shutdown" so that we won't error out
and get stuck, if we ever hit weird state transitions
like this again." |
| In the Linux kernel, the following vulnerability has been resolved:
net: xilinx: axienet: Fix BQL accounting for multi-BD TX packets
When a TX packet spans multiple buffer descriptors (scatter-gather),
axienet_free_tx_chain sums the per-BD actual length from descriptor
status into a caller-provided accumulator. That sum is reset on each
NAPI poll. If the BDs for a single packet complete across different
polls, the earlier bytes are lost and never credited to BQL. This
causes BQL to think bytes are permanently in-flight, eventually
stalling the TX queue.
The SKB pointer is stored only on the last BD of a packet. When that
BD completes, use skb->len for the byte count instead of summing
per-BD status lengths. This matches netdev_sent_queue(), which debits
skb->len, and naturally survives across polls because no partial
packet contributes to the accumulator. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/zcrx: fix sgtable leak on mapping failures
In an unlikely case when io_populate_area_dma() fails, which could only
happen on a PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA machine,
io_zcrx_map_area() will have an initialised and not freed table. It was
supposed to be cleaned up in the error path, but !is_mapped prevents
that. |
