DESCRIPTION

* CVE-2024-1086: Privilege escalation in netfilter subsystem.

Missing check on user input in netfilter subsystem could lead to a
double free. A local attacker could use this flaw to cause a denial-
of-service or escalate privilege.


* CVE-2023-45863: Out-of-bounds write in a library routine for handling generic kernel objects.

Handling of internal kernel objects can race, leading to an
out-of-bounds write. An attacker with root access can exploit
this to cause denial-of-service or aid in other types of attacks.
