| In the Linux kernel, the following vulnerability has been resolved:
NFS: Check the TLS certificate fields in nfs_match_client()
If the TLS security policy is of type RPC_XPRTSEC_TLS_X509, then the
cert_serial and privkey_serial fields need to match as well since they
define the client's identity, as presented to the server. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: fix workqueue leak on bind errors
Make sure to destroy the workqueue also in case of early errors during
bind (e.g. a subcomponent failing to bind).
Since commit c3b790ea07a1 ("drm: Manage drm_mode_config_init with
drmm_") the mode config will be freed when the drm device is released
also when using the legacy interface, but add an explicit cleanup for
consistency and to facilitate backporting.

The issue was reported on 12th of August and was ignored by author of
commits introducing issue for two weeks. Only after complaining author
produced a fix which did not work, so if original commits cannot be
reliably fixed for 5 weeks, they obviously are buggy and need to be
dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
cpufreq: qcom: fix memory leak in error path
If for some reason the speedbin length is incorrect, then there is a
memory leak in the error path because we never free the speedbin buffer.
This commit fixes the error path to always free the speedbin buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: core: Fix kernel panic when remove non-standard SDIO card
SDIO tuple is only allocated for standard SDIO card, especially it causes
memory corruption issues when the non-standard SDIO card has removed, which
is because the card device's reference counter does not increase for it at
sdio_init_func(), but all SDIO card device reference counter gets decreased
at sdio_release_func(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix skb leak by txs missing in AMSDU
txs may be dropped if the frame is aggregated in AMSDU. When the problem
shows up, some SKBs would be hold in driver to cause network stopped
temporarily. Even if the problem can be recovered by txs timeout handling,
mt7921 still need to disable txs in AMSDU to avoid this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/plane: Fix create_in_format_blob() return value
create_in_format_blob() is either supposed to return a valid
pointer or an error, but never NULL. The caller will dereference
the blob when it is not an error, and thus will oops if NULL
returned. Return proper error values in the failure cases. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Fix null pointer dereference in bnxt_bs_trace_check_wrap()
With older FW, we may get the ASYNC_EVENT_CMPL_EVENT_ID_DBG_BUF_PRODUCER
for FW trace data type that has not been initialized. This will result
in a crash in bnxt_bs_trace_type_wrap(). Add a guard to check for a
valid magic_byte pointer before proceeding. |
| In the Linux kernel, the following vulnerability has been resolved:
net: do not allow gso_size to be set to GSO_BY_FRAGS
One missing check in virtio_net_hdr_to_skb() allowed
syzbot to crash kernels again [1]
Do not allow gso_size to be set to GSO_BY_FRAGS (0xffff),
because this magic value is used by the kernel.

ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove
The MBHC resources must be released on component probe failure and
removal so can not be tied to the lifetime of the component device.
This is specifically needed to allow probe deferrals of the sound card
which otherwise fails when reprobing the codec component:

drm/i915: Fix NULL ptr deref by checking new_crtc_state
intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't
obtained previously with intel_atomic_get_crtc_state, so we must check it
for NULLness here, just as in many other places, where we can't guarantee
that intel_atomic_get_crtc_state was called.
We are currently getting NULL ptr deref because of that, so this fix was
confirmed to help.

The buggy address belongs to the object at ffff88802e08ed00
which belongs to the cache skbuff_small_head of size 640
The buggy address is located 194 bytes inside of
freed 640-byte region [ffff88802e08ed00, ffff88802e08ef80)
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: release path before inode lookup during the ino lookup ioctl
During the ino lookup ioctl we can end up calling btrfs_iget() to get an
inode reference while we are holding on a root's btree. If btrfs_iget()
needs to lookup the inode from the root's btree, because it's not
currently loaded in memory, then it will need to lock another or the
same path in the same root btree. This may result in a deadlock and
trigger the following lockdep splat:

| In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix lost destroy smbd connection when MR allocate failed
If the MR allocate failed, the smb direct connection info is NULL,
then smbd_destroy() will directly return, then the connection info

| In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: ep: Only send -ENOTCONN status if client driver is available
For the STOP and RESET commands, only send the channel disconnect status
-ENOTCONN if client driver is available. Otherwise, it will result in
null pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Array index may go out of bound

16..19. Use snprintf() instead of sprintf(). |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: xiic: xiic_xfer(): Fix runtime PM leak on error path
The xiic_xfer() function gets a runtime PM reference when the function is
entered. This reference is released when the function is exited. There is
currently one error path where the function exits directly, which leads to
a leak of the runtime PM reference.
Make sure that this error path also releases the runtime PM reference. |

The usb function device call musb_gadget_queue() adds the passed
request to musb_ep::req_list,If the (request->length > musb_ep->packet_sz)
and (is_buffer_mapped(req) return false),the rxstate() will copy all data
in fifo to request->buf which may cause request->buf out of bounds.
Fix it by add the length check :
fifocnt = min_t(unsigned, request->length - request->actual, fifocnt); |
| In the Linux kernel, the following vulnerability has been resolved:
net: broadcom: bcm4908_enet: update TX stats after actual transmission
Queueing packets doesn't guarantee their transmission. Update TX stats
after hardware confirms consuming submitted data.
This also fixes a possible race and NULL dereference.
bcm4908_enet_start_xmit() could try to access skb after freeing it in
the bcm4908_enet_poll_tx(). |
