CVE-2022-48998

A flaw was found in the Linux kernel's BPF (Berkeley Packet Filter) subsystem for PowerPC 32-bit architectures. A local attacker could exploit this vulnerability by executing a specially crafted BPF program that utilizes tail calls with differing stack depths. This improper handling of stack frames can lead to an out-of-bounds write on the kernel stack. Successful exploitation could result in a kernel crash, leading to a denial of service, and potentially allow for privilege escalation or information disclosure.
