Ubuntu Security Notice USN-5644-1
Posted Sep 28, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5644-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service.
