Summary

linux-oem-5.14 vulnerabilities

Details

Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges. (CVE-2022-0492)

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)

Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2021-44879)

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)

Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to open a directory on a regular file. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-24448)

It was discovered that the YAM AX.25 device driver in the Linux kernel did not properly deallocate memory in some error conditions. A local privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2022-24959)
