A double-free memory corruption in the Linux kernel HCI device
initialization subsystem was found in the way user attach malicious HCI
TTY Bluetooth device. A local user could use this flaw to crash the system
(CVE-2021-3564).
kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect
limits for pointer arithmetic operations. This can be abused to perform
out-of-bounds reads and writes in kernel memory, leading to local privilege
escalation to root. In particular, there is a corner case where the off reg
causes a masking direction change, which then results in an incorrect final
aux->alu_limit (CVE-2021-33200).
Other fixes in this update:
- proc: Check /proc/$pid/attr/ writes against file opener
For other upstream fixes, see the referenced changelogs.");
