Red Hat Security Advisory: kernel security, bug fix, and enhancement update
Red Hat has released a security advisory addressing multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 9.6 Extended Update Support. The update fixes several security issues including use-after-free bugs, information leaks, out-of-bounds reads, and validation errors across various kernel components such as VMCI, virtual terminal, Bluetooth, AMD display, SMB client, network scheduler, and DRM. The advisory also includes bug fixes and enhancements unrelated to security. Systems must be rebooted after applying the update for changes to take effect.
