Multiple security vulnerabilities were discovered in the linux-oem-7.0 kernel, including a critical issue affecting AMD Zen 2 processors where improper isolation of shared resources in the operation cache could allow a local attacker to corrupt higher privilege instructions, leading to privilege escalation. Numerous other flaws across various kernel subsystems were also addressed in this update. The vulnerabilities could potentially allow attackers to compromise the system. A patch is available and users are advised to update and reboot their systems.
