Summary
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: watch queue race condition can lead to privilege escalation (CVE-2022-2959)
* kernel: memory corruption in AX88179_178A based USB ethernet device. (CVE-2022-2964)
* kernel: i915: Incorrect GPU TLB flush can lead to random memory access (CVE-2022-4139)
* kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945)
* kernel: i2c: unbounded length leads to buffer overflow in ismt_access() (CVE-2022-3077)
* kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594)
