CVSS v3.1 |
| 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:
powerpc/secvar: fix refcount leak in format_show()
Refcount leak will happen when format_show returns failure in multiple
cases. Unified management of of_node_put can fix this problem. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: Fix memory leaks on probe
Handle the error branches to free memory where required.
Addresses-Coverity-ID: 1491825 ("Resource leak") |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: fix memory leak in ceph_readdir when note_last_dentry returns error
Reset the last_readdir at the same time, and add a comment explaining
why we don't free last_readdir when dir_emit returns false. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: wfx: fix an error handling in wfx_init_common()
One error handler of wfx_init_common() return without calling
ieee80211_free_hw(hw), which may result in memory leak. And I add
one err label to unify the error handler, which is useful for the
subsequent changes. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix reference count leaks in _nfs42_proc_copy_notify()
[You don't often get email from xiongx18@fudan.edu.cn. Learn why this is important at http://aka.ms/LearnAboutSenderIdentification.]
The reference counting issue happens in two error paths in the
function _nfs42_proc_copy_notify(). In both error paths, the function
simply returns the error code and forgets to balance the refcount of
object `ctx`, bumped by get_nfs_open_context() earlier, which may
cause refcount leaks.
Fix it by balancing refcount of the `ctx` object before the function
returns in both error paths. |
| 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:
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: 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.
Addresses-Coverity: 1494120 ("Resource leak") |
| In the Linux kernel, the following vulnerability has been resolved:
samples/landlock: Fix path_list memory leak
Clang static analysis reports this error
sandboxer.c:134:8: warning: Potential leak of memory
pointed to by 'path_list'
ret = 0;
^
path_list is allocated in parse_path() but never freed. |
| In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Fix a memory leak in 'host1x_remove()'
Add a missing 'host1x_channel_list_free()' call in the remove function,
as already done in the error handling path of the probe function. |
| In the Linux kernel, the following vulnerability has been resolved:
media: staging: media: zoran: move videodev alloc
Move some code out of zr36057_init() and create new functions for handling
zr->video_dev. This permit to ease code reading and fix a zr->video_dev
memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/sched: Fix fence reference count leak
The last_scheduled fence leaks when an entity is being killed and adding
the cleanup callback fails.
Decrement the reference count of prev when dma_fence_add_callback()
fails, ensuring proper balance.
[phasta: add git tag info for stable kernel] |
| In the Linux kernel, the following vulnerability has been resolved:
mm/huge_memory: drop beyond-EOF folios with the right number of refs
When an after-split folio is large and needs to be dropped due to EOF,
folio_put_refs(folio, folio_nr_pages(folio)) should be used to drop all
page cache refs. Otherwise, the folio will not be freed, causing memory
leak.
This leak would happen on a filesystem with blocksize > page_size and a
truncate is performed, where the blocksize makes folios split to >0 order
ones, causing truncated folios not being freed. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "wifi: mac80211: fix memory leak in ieee80211_if_add()"
This reverts commit 13e5afd3d773c6fc6ca2b89027befaaaa1ea7293.
ieee80211_if_free() is already called from free_netdev(ndev)
because ndev->priv_destructor == ieee80211_if_free

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Fix memory leaks
When hci_cmd_sync_queue() failed in hci_le_terminate_big() or
hci_le_big_terminate(), the memory pointed by variable d is not freed,
which will cause memory leak. Add release process to error path. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: fix memory leak in hci_update_adv_data()
When hci_cmd_sync_queue() failed in hci_update_adv_data(), inst_ptr is
not freed, which will cause memory leak, convert to use ERR_PTR/PTR_ERR
to pass the instance to callback so no memory needs to be allocated. |

To fix this the patch rearranges the goto labels to reflect the order of
object allocations and adds appropriate goto statements on the error
paths.

EDAC/highbank: Fix memory leak in highbank_mc_probe()
When devres_open_group() fails, it returns -ENOMEM without freeing memory
allocated by edac_mc_alloc().
Call edac_mc_free() on the error handling path to avoid a memory leak.
