USN-5339-1: Linux kernel vulnerabilities

Published Mar 22, 2022
·
Updated

Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 releaseagent feature. A local attacker could use this to gain administrative privileges. (CVE-2022-0492) It was discovered that an out-of-bounds (OOB) memory access flaw existed in the f2fs module of the Linux kernel. A local attacker could use this issue to cause a denial of service (system crash). (CVE-2021-3506) Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976) It was discovered that the ARM Trusted Execution Environment (TEE) subsystem in the Linux kernel contained a race condition leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-44733) It was discovered that the Phone Network protocol (PhoNet) implementation in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45095) Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435)
