{"id":"ALSA-2022:5249","summary":"Important: kernel security and bug fix update","details":"The kernel packages contain the Linux kernel, the core of any Linux operating system.\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* make SHA512_arch algos and CRYPTO_USER built-ins (BZ#2072643)\n* SR-IOV performance \u003e 50% degradation (BZ#2074830)\n* fix data corruption caused by dm-integrity
