This Red Hat security advisory addresses multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 9. The update fixes issues including double free, use-after-free, out-of-bounds reads, variable overflow, and uninitialized memory access across various kernel components such as media (uvcvideo), wifi (iwlwifi), RDMA, ext4 filesystem, network scheduling, and memory management. The advisory rates the overall security impact as moderate. Systems must be updated and rebooted to apply the fixes.
