| In the Linux kernel, the following vulnerability has been resolved:
amt: fix possible memory leak in amt_rcv()
If an amt receives packets and it finds socket.
If it can't find a socket, it should free a received skb.
But it doesn't.
So, a memory leak would possibly occur. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix reference count leak in smb_check_perm_dacl()
The issue happens in a specific path in smb_check_perm_dacl(). When
"id" and "uid" have the same value, the function simply jumps out of
the loop without decrementing the reference count of the object
"posix_acls", which is increased by get_acl() earlier. This may
result in memory leaks.
Fix it by decreasing the reference count of "posix_acls" before
jumping to label "check_access_bits". |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: memleak flow rule from commit path
Abort path release flow rule object, however, commit path does not.
Update code to destroy these objects before releasing the transaction. |
| In the Linux kernel, the following vulnerability has been resolved:
jffs2: fix memory leak in jffs2_do_mount_fs
If jffs2_build_filesystem() in jffs2_do_mount_fs() returns an error,
we can observe the following kmemleak report:

--------------------------------------------
This is because the resources allocated in jffs2_sum_init() are not
released. Call jffs2_sum_exit() to release these resources to solve
the problem. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: mxs: Fix error handling in mxs_sgtl5000_probe
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]
are not NULL, it will cause leaks.
of_node_put() will check if the node pointer is NULL, so we can
call it directly to release the refcount of regular pointers. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Call dc_stream_release for remove link enc assignment
[Why]
A porting error resulted in the stream assignment for the link
being retained without being released - a memory leak.
[How]
Fix the porting error by adding back the dc_stream_release() intended
as part of the original patch. |
| In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7915: fix possible memory leak in mt7915_mcu_add_sta
Free allocated skb in mt7915_mcu_add_sta routine in case of failures. |
| In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7921s: fix a possible memory leak in mt7921_load_patch
Always release fw data at the end of mt7921_load_patch routine. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: ab8500: Fix memory leak in ab8500_fg_sysfs_init
kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add():
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object.
Fix memory leak by calling kobject_put(). |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix memory leak in error flow for subscribe event routine
In case the second xa_insert() fails, the obj_event is not released. Fix
the error unwind flow to free that memory to avoid a memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
wireguard: socket: free skb in send6 when ipv6 is disabled
I got a memory leak report:

In function wg_socket_send_buffer_as_reply_to_skb() or wg_socket_send_
buffer_to_peer(), the semantics of send6() is required to free skb. But
when CONFIG_IPV6 is disable, kfree_skb() is missing. This patch adds it
to fix this bug. |
| In the Linux kernel, the following vulnerability has been resolved:
watch_queue: Free the page array when watch_queue is dismantled
Commit 7ea1a0124b6d ("watch_queue: Free the alloc bitmap when the
watch_queue is torn down") took care of the bitmap, but not the page
array.

| In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix memory leak of uid in files registration
When there are no files for __io_sqe_files_scm() to process in the
range, it'll free everything and return. However, it forgets to put uid. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: use memset avoid memory leaks
Use memset to initialize structs to prevent memory leaks
in l2cap_ecred_connect |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Fix misused goto label
Fix a misused goto label jump since that can result in a memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
habanalabs: fix possible memory leak in MMU DR fini
This patch fixes what seems to be copy paste error.
We will have a memory leak if the host-resident shadow is NULL (which
will likely happen as the DR and HR are not dependent). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix a potential gpu_metrics_table memory leak
Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(),
but not freed in int smu_v12_0_fini_smc_tables(). Free it! |
| In the Linux kernel, the following vulnerability has been resolved:
media: venus: vdec: fixed possible memory leak issue
The venus_helper_alloc_dpb_bufs() implementation allows an early return
on an error path when checking the id from ida_alloc_min() which would
not release the earlier buffer allocation.
Move the direct kfree() from the error checking of dma_alloc_attrs() to
the common fail path to ensure that allocations are released on all
error paths in this function.

samples/landlock: Fix path_list memory leak
Clang static analysis reports this error
sandboxer.c:134:8: warning: Potential leak of memory
