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).
