{"id":"ALSA-2022:5267","summary":"Important: kernel-rt security and bug fix update","details":"The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\nSecurity Fix(es):\n* kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)\n* kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)\n* kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966)\n* kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\nBug Fix(es):\n* kernel-rt: update RT source tree to the latest AlmaLinux-9.0.z1 Batch
