Important: kernel-rt security update

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fixes: kernel: bpf: Don't use tnumrange on array range checking for poke descriptors CVE-2022-49985 kernel: posix-cpu-timers: fix race between...

CVE-2022-49985

The CVE-2022-49985 entry concerns the Linux kernel, where the BPF component allowed a range check descriptor to misrepresent a tight range because tnum_range(0, map->max_entries-1) may yield a superset of the intended values. The root cause is that the tnum-based range representation can erron...
