| In the Linux kernel, the following vulnerability has been resolved:
PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y
After a pci_doe_task completes, its work_struct needs to be destroyed
to avoid a memory leak with CONFIG_DEBUG_OBJECTS=y. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: ocb: don't leave if not joined
If there's no OCB state, don't ask the driver/mac80211 to
leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check. |
| In the Linux kernel, the following vulnerability has been resolved:
ipc: mqueue: fix possible memory leak in init_mqueue_fs()
commit db7cfc380900 ("ipc: Free mq_sysctls if ipc namespace creation
failed")
Here's a similar memory leak to the one fixed by the patch above.
retire_mq_sysctls need to be called when init_mqueue_fs fails after
setup_mq_sysctls. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-crypto: fix memory leak in virtio_crypto_alg_skcipher_close_session()
'vc_ctrl_req' is alloced in virtio_crypto_alg_skcipher_close_session(),
and should be freed in the invalid ctrl_status->status error handling
case. Otherwise there is a memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
net/ieee802154: don't warn zero-sized raw_sendmsg()
syzbot is hitting skb_assert_len() warning at __dev_queue_xmit() [1],
for PF_IEEE802154 socket's zero-sized raw_sendmsg() request is hitting
__dev_queue_xmit() with skb->len == 0.
Since PF_IEEE802154 socket's zero-sized raw_sendmsg() request was
able to return 0, don't call __dev_queue_xmit() if packet length is 0.
----------
#include <sys/socket.h>
#include <netinet/in.h>
int main(int argc, char *argv[])
{
struct sockaddr_in addr = { .sin_family = AF_INET, .sin_addr.s_addr = htonl(INADDR_LOOPBACK) };
struct iovec iov = { };
struct msghdr hdr = { .msg_name = &addr, .msg_namelen = sizeof(addr), .msg_iov = &iov, .msg_iovlen = 1 };
sendmsg(socket(PF_IEEE802154, SOCK_RAW, 0), &hdr, 0);
return 0;
}
----------
Note that this might be a sign that commit fd1894224407c484 ("bpf: Don't
redirect packets with invalid pkt_len") should be reverted, for
skb->len == 0 was acceptable for at least PF_IEEE802154 socket. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid0, raid10: Don't set discard sectors for request queue
It should use disk_stack_limits to get a proper max_discard_sectors
rather than setting a value by stack drivers.
And there is a bug. If all member disks are rotational devices,
raid0/raid10 set max_discard_sectors. So the member devices are
not ssd/nvme, but raid0/raid10 export the wrong value. It reports
warning messages in function __blkdev_issue_discard when mkfs.xfs
like this:

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios()
As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.
If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: hpsa: Fix possible memory leak in hpsa_init_one()
The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in
hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to
clean1 directly, which frees h and leaks the h->reply_map.
Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead
free h directly. |
| In the Linux kernel, the following vulnerability has been resolved:
net: vxlan: prevent NULL deref in vxlan_xmit_one
Neither sock4 nor sock6 pointers are guaranteed to be non-NULL in
vxlan_xmit_one, e.g. if the iface is brought down. This can lead to the
following NULL dereference:
BUG: kernel NULL pointer dereference, address: 0000000000000010
Oops: Oops: 0000 [#1] SMP NOPTI
RIP: 0010:vxlan_xmit_one+0xbb3/0x1580

Mentioned commits changed the code path in vxlan_xmit_one and as a side
effect the sock4/6 pointer validity checks in vxlan(6)_get_route were
lost. Fix this by adding back checks.
Since both commits being fixed were released in the same version (v6.7)
and are strongly related, bundle the fixes in a single commit. |
| In the Linux kernel, the following vulnerability has been resolved:
regulator: core: Protect regulator_supply_alias_list with regulator_list_mutex
regulator_supply_alias_list was accessed without any locking in
regulator_supply_alias(), regulator_register_supply_alias(), and
regulator_unregister_supply_alias(). Concurrent registration,
unregistration and lookups can race, leading to:
1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.
Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex. |
| In the Linux kernel, the following vulnerability has been resolved:

If a panic is triggered by a hrtimer interrupt all online cpus will be
notified and set offline. But as highlighted by commit 19dbdcb8039c

drm/stm: ltdc: fix late dereference check
In ltdc_crtc_set_crc_source(), struct drm_crtc was dereferenced in a
container_of() before the pointer check. This could cause a kernel panic.
Fix this smatch warning:
drivers/gpu/drm/stm/ltdc.c:1124 ltdc_crtc_set_crc_source() warn: variable dereferenced before check 'crtc' (see line 1119) |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: cfg80211: Pass the PMK in binary instead of hex
Apparently the hex passphrase mechanism does not work on newer
chips/firmware (e.g. BCM4387). It seems there was a simple way of
passing it in binary all along, so use that and avoid the hexification.
OpenBSD has been doing it like this from the beginning, so this should
work on all chips.
Also clear the structure before setting the PMK. This was leaking
uninitialized stack contents to the device. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()
The rtl8187_rx_cb() calculates the rx descriptor header address
by subtracting its size from the skb tail pointer.
However, it does not validate if the received packet
(skb->len from urb->actual_length) is large enough to contain this
header.
If a truncated packet is received, this will lead to a buffer
underflow, reading memory before the start of the skb data area,
and causing a kernel panic.
Add length checks for both rtl8187 and rtl8187b descriptor headers
before attempting to access them, dropping the packet cleanly if the
check fails. |
| In the Linux kernel, the following vulnerability has been resolved:
macintosh/mac_hid: fix race condition in mac_hid_toggle_emumouse
The following warning appears when running syzkaller, and this issue also
exists in the mainline code.

| In the Linux kernel, the following vulnerability has been resolved:
coresight: ETR: Fix ETR buffer use-after-free issue
When ETR is enabled as CS_MODE_SYSFS, if the buffer size is changed
and enabled again, currently sysfs_buf will point to the newly
allocated memory(buf_new) and free the old memory(buf_old). But the
etr_buf that is being used by the ETR remains pointed to buf_old, not
updated to buf_new. In this case, it will result in a memory
use-after-free issue.
Fix this by checking ETR's mode before updating and releasing buf_old,
if the mode is CS_MODE_SYSFS, then skip updating and releasing it. |
| In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe()
In hfcsusb_probe(), the memory allocated for ctrl_urb gets leaked when
setup_instance() fails with an error code. Fix that by freeing the urb
before freeing the hw structure. Also change the error paths to use the
goto ladder style.
Compile tested only. Issue found using a prototype static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: Fix uninit buffer allocated by __getname()
Fix uninit errors caused after buffer allocation given to 'de'; by
initializing the buffer with zeroes. The fix was found by using KMSAN. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64/pageattr: Propagate return value from __change_memory_common
The rodata=on security measure requires that any code path which does
vmalloc -> set_memory_ro/set_memory_rox must protect the linear map alias
too. Therefore, if such a call fails, we must abort set_memory_* and caller
must take appropriate action; currently we are suppressing the error, and
there is a real chance of such an error arising post commit a166563e7ec3
("arm64: mm: support large block mapping when rodata=full"). Therefore,
propagate any error to the caller. |
| Improper handling of the authentication token in the Amazon WorkSpaces client for Linux, versions 2023.0 through 2024.8, may expose the authentication token for DCV-based WorkSpaces to other local users on the same client machine. Under certain circumstances, a local user may be able to extract another local user's authentication token from the shared client machine and access their WorkSpace.
To mitigate this issue, users should upgrade to the Amazon WorkSpaces client for Linux version 2025.0 or later. |
