Multiple security vulnerabilities were discovered in the Linux kernel for Raspberry Pi systems, affecting GPU drivers and the Sun RPC protocol. These flaws could potentially allow an attacker to compromise the system. A patch fixing these issues is available in version 5.15.0-1079.82 of the linux-raspi kernel package. Users are advised to update and reboot their systems to apply the fixes. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled after the update.
