The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * a use-after-free in cls_route filter implementation may lead to privilege escalation * RetBleed Arbitrary Speculative Code Execution with Return Instructions * Branch Type Confusion * Intel: Post-barrier Return Stack Buffer Predictions * Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * lpfc panics in lpfc_els_free_iocb during port recovery * mlx5 reports error messages during shutdown then panic with mce * Kernel panic due to hard lockup caused by deadlock between tasklist_lock and k_itimer it_lock * fix excess double put in nfs_prime_dcache 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
