description-logoDescription

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729) kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966) kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729) kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966) kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) For 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.
