Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-22942)

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

The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.

Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.


2) Heap-based buffer overflow (CVE-ID: CVE-2022-27666)

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

The vulnerability exists due to a boundary error within IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c in Linux kernel. A local unprivileged user can pass specially crafted data to the system, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
