Description

This kernel-linus update is based on upstream 5.10.62 and fixes at least the
following security issues:

Specifically timed and handcrafted traffic can cause internal errors
in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a
consequent possibility of information disclosure over the air for a
discrete set of traffic in ath9k (CVE-2020-3702).

A process with CAP_SYS_ADMIN can cause a kernel NULL pointer dereference
in btrfs code (CVE-2021-3739).

there is an out-of-bound read bug in qrtr_endpoint_post in net/qrtr/qrtr.c
(CVE-2021-3743).

An out-of-bounds read due to a race condition has been found in the Linux
kernel due to write access to vc_mode is not protected by a lock in vt_ioctl
(KDSETMDE) (CVE-2021-3753).

For other upstream fixes, see the referenced changelogs.
