Summary
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: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)
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.
