| Description: | The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
kernel: improper initialization of the "flags" member of the new pipe_buffer (CVE-2022-0847)
kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)
kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154)
kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)
kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)
kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492)
kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
