25 Mar 2022 — A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system.

18 Mar 2022 — In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. En el kernel de Linux versiones anteriores a 5.15.3, el archivo fs/quota/quota_tree.c no comprueba el número de bloque en el árbol de cuotas (en disco).
