| In the Linux kernel, the following vulnerability has been resolved:
net: bcmgenet: fix leaking free_bds
While reclaiming the tx queue we fast forward the write pointer to
drop any data in flight. These dropped frames are not added back
to the pool of free bds. We also need to tell the netdev that we
are dropping said data. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: master: renesas: Fix memory leak in renesas_i3c_i3c_xfers()
The xfer structure allocated by renesas_i3c_alloc_xfer() was never freed
in the renesas_i3c_i3c_xfers() function. Use the __free(kfree) cleanup
attribute to automatically free the memory when the variable goes out of
scope. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Fix vaddr leak when indirect CSD has zeroed workgroups
v3d_rewrite_csd_job_wg_counts_from_indirect() maps both the indirect
buffer and the workgroup buffer and is expected to release them before
returning. When any of the workgroup counts read from the buffer is zero,
the function bailed out early and skipped the cleanup, leaking the vaddr
mappings of both BOs.
Jump to the cleanup path instead of returning directly, so the mappings
are always dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_meta_bridge: fix stale stack leak via IIFHWADDR register
NFT_META_BRI_IIFHWADDR declares its destination register with
len = ETH_ALEN (6 bytes), which the register-init tracking rounds up to
two 32-bit registers (8 bytes). nft_meta_bridge_get_eval() then does
memcpy(dest, br_dev->dev_addr, ETH_ALEN), writing only 6 bytes and
leaving the upper 2 bytes of the second register as uninitialised
nft_do_chain() stack. A downstream load of that register span leaks
those stale bytes to userspace.
Zero the second register before the memcpy so the full declared span is
written. |
| A denial-of-service security issue exists within the 1794-AENTR adapter due to improper memory handling of CIP protocol requests. This vulnerability can result in the adapter faulting and losing connection to its associated I/O modules, requiring a manual reset to recover. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: sti: use managed regmap_field allocations
The regmap_field objects allocated at player init are never freed and
may leak resources if the driver is removed.
Switch to devm_regmap_field_alloc() to automatically limit the lifetime
of the allocations the lifetime of the device. |
| A vulnerability was found in the Infinispan component in Red Hat Data Grid. The REST compare API may have a buffer leak and an out of memory error can occur when sending continual requests with large POST data to the REST API. |
| In the Linux kernel, the following vulnerability has been resolved:
tee: shm: fix shm leak in register_shm_helper()
register_shm_helper() allocates shm before calling
iov_iter_npages(). If iov_iter_npages() returns 0, the function
jumps to err_ctx_put and leaks shm.
This can be triggered by TEE_IOC_SHM_REGISTER with
struct tee_ioctl_shm_register_data where length is 0.
Jump to err_free_shm instead. |
| In the Linux kernel, the following vulnerability has been resolved:
block: fix zones_cond memory leak on zone revalidation error paths
When blk_revalidate_disk_zones() fails after disk_revalidate_zone_resources()
has allocated args.zones_cond, the memory is leaked because no error path
frees it. |
| In the Linux kernel, the following vulnerability has been resolved:
net_sched: fix skb memory leak in deferred qdisc drops
When the network stack cleans up the deferred list via qdisc_run_end(),
it operates on the root qdisc. If the root qdisc do not implement the
TCQ_F_DEQUEUE_DROPS flag the packets queue to free are never freed and
gets stranded on the child's local to_free list.
Fix this by making qdisc_dequeue_drop() aware of the root qdisc. It
fetches the root qdisc and check for the TCQ_F_DEQUEUE_DROPS flag. If
the flag is present, the packet is appended directly to the root's
to_free list. Otherwise, drop it directly as it was done before the
optimization was implemented. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix durable fd leak on ClientGUID mismatch in durable v2 open
ksmbd_lookup_fd_cguid() returns a ksmbd_file with its refcount
incremented via ksmbd_fp_get(). parse_durable_handle_context() in
the DURABLE_REQ_V2 case properly releases this reference on every
path inside the ClientGUID-match branch, either by calling
ksmbd_put_durable_fd() or by transferring ownership to dh_info->fp
for a successful reconnect. However, when an entry exists in the
global file table with the same CreateGuid but a different
ClientGUID, the code simply falls through to the new-open path
without dropping the reference obtained from ksmbd_lookup_fd_cguid().
Per MS-SMB2 section 3.3.5.9.10 ("Handling the
SMB2_CREATE_DURABLE_HANDLE_REQUEST_V2 Create Context"), the server
MUST locate an Open whose Open.CreateGuid matches the request's
CreateGuid AND whose Open.ClientGuid matches the ClientGuid of the
connection that received the request. If no such Open is found, the
server MUST continue with the normal open execution phase. A
CreateGuid hit with a ClientGUID mismatch is therefore the
"Open not found" case: proceeding with a new open is correct, but
the reference obtained purely as a side effect of the lookup must
not be leaked.
Repeated requests that hit this mismatch pin global_ft entries,
prevent __ksmbd_close_fd() from ever running for the corresponding
files, and defeat the durable scavenger, leading to long-lived
resource leaks.
Release the reference in the mismatch path and clear dh_info->fp so
subsequent logic does not mistake a non-matching lookup result for
a reconnect target. |
| ImageMagick before 7.1.2-15 contains a memory leak vulnerability in multiple coders that write raw pixel data where allocated objects are not properly freed. Attackers can trigger this leak by processing specially crafted images, causing memory exhaustion and denial of service. |
| There is a memory leak in NI grpc-device BeginSidebandStream that may result in denial of service due to memory exhaustion. This affects NI grpc-device 2.17.0 and prior versions. |
| In the Linux kernel, the following vulnerability has been resolved:
EDAC/versalnet: Fix device_node leak in mc_probe()
of_parse_phandle() returns a device_node reference that must be released with
of_node_put(). The original code never freed r5_core_node on any exit path,
causing a memory leak.
Fix this by using the automatic cleanup attribute __free(device_node) which
ensures of_node_put() is called when the variable goes out of scope. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: atmel-aes - Fix 3-page memory leak in atmel_aes_buff_cleanup
atmel_aes_buff_init() allocates 4 pages using __get_free_pages() with
ATMEL_AES_BUFFER_ORDER, but atmel_aes_buff_cleanup() frees only the
first page using free_page(), leaking the remaining 3 pages. Use
free_pages() with ATMEL_AES_BUFFER_ORDER to fix the memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/mempolicy: fix memory leaks in weighted_interleave_auto_store()
weighted_interleave_auto_store() fetches old_wi_state inside the if
(!input) block only. This causes two memory leaks:
1. When a user writes "false" and the current mode is already manual,
the function returns early without freeing the freshly allocated
new_wi_state.
2. When a user writes "true", old_wi_state stays NULL because the
fetch is skipped entirely. The old state is then overwritten by
rcu_assign_pointer() but never freed, since the cleanup path is
gated on old_wi_state being non-NULL. A user can trigger this
repeatedly by writing "1" in a loop.
Fix both leaks by moving the old_wi_state fetch before the input check,
making it unconditional. This also allows a unified early return for both
"true" and "false" when the requested mode matches the current mode.

crypto: ccree - fix a memory leak in cc_mac_digest()
Add cc_unmap_result() if cc_map_hash_request_final()
fails to prevent potential memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Fix memory leak in starfive_aes_aead_do_one_req()
The starfive_aes_aead_do_one_req() function allocates rctx->adata with
kzalloc() but fails to free it if sg_copy_to_buffer() or
starfive_aes_hw_init() fails, which lead to memory leaks.
Since rctx->adata is unconditionally freed after the write_adata
operations, ensure consistent cleanup by freeing the allocation in these
earlier error paths as well.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |

fbdev: au1200fb: Fix a memory leak in au1200fb_drv_probe()
In au1200fb_drv_probe(), when platform_get_irq fails(), it directly
returns from the function with an error code, which causes a memory
leak.
Replace it with a goto label to ensure proper cleanup. |

lib/scatterlist: fix length calculations in extract_kvec_to_sg
Patch series "Fix bugs in extract_iter_to_sg()", v3.
Fix bugs in the kvec and user variants of extract_iter_to_sg. This series
is growing due to useful remarks made by sashiko.dev.
The main bugs are:
- The length for an sglist entry when extracting from
a kvec can exceed the number of bytes in the page. This
is obviously not intended.
- When extracting a user buffer the sglist is temporarily
used as a scratch buffer for extracted page pointers.
If the sglist already contains some elements this scratch
buffer could overlap with existing entries in the sglist.
The series adds test cases to the kunit_iov_iter test that demonstrate all
of these bugs. Additionally, there is a memory leak fix for the test
itself.
The bugs were orignally introduced into kernel v6.3 where the function
lived in fs/netfs/iterator.c. It was later moved to lib/scatterlist.c in
v6.5. Thus the actual fix is only marked for backports to v6.5+.
This patch (of 5):
When extracting from a kvec to a scatterlist, do not cross page
boundaries. The required length was already calculated but not used as
intended.
Adjust the copied length if the loop runs out of sglist entries without
extracting everything.
While there, return immediately from extract_iter_to_sg if there are no
sglist entries at all.
A subsequent commit will add kunit test cases that demonstrate that the
patch is necessary. |
