Buffer overflow in Linux kernel - CVE-2022-32981

Vulnerability identifier: #VU65005

CSH Severity: Low

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-32981

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in ptrace PEEKUSER and POKEUSER when accessing floating point registers on powerpc 32-bit platforms. A local user can trigger buffer overflow and execute arbitrary code with elevated privileges.
