Red Hat has released an important security advisory addressing multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 9.6 Extended Update Support. The update fixes several use-after-free vulnerabilities, denial of service issues, and other kernel bugs affecting components such as smc, libceph, netfilter, xfs, memory management, net scheduling, SMB client, RDMA, and wifi mac80211. The advisory also includes bug fixes and performance enhancements. Systems must be rebooted after applying the update for changes to take effect.
