Arm Mali GPU Kernel Driver Use-After-Free Vulnerability (CVE-2021-29256)

A remote attacker, with a low-privilege account, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2023-07-28 under CISA BOD 22-01.

This is a Use After Free (CWE-416) vulnerability in Arm Mali Graphics Processing Unit (GPU). . The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0. Exploitation requires remote network access, low attack complexity, a low-privilege authenticated account, and no user interaction required.

Probably yes if any of these apply:

CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2023-07-07 based on evidence of active exploitation in the wild. Federal agencies required to remediate by 2023-07-28.
