Red Hat Security Advisory: kpatch-patch-5_14_0-427_13_1 and kpatch-patch-5_14_0-427_31_1 security update
Red Hat has released a security advisory for a kernel live patch module targeting kernel-5.14.0-427.13.1.el9_4. The update addresses two denial of service vulnerabilities (CVE-2024-41090 and CVE-2024-41091) related to the virtio-net tap and tun drivers interacting with mlx5_core. These vulnerabilities could allow denial of service via short frame handling. The advisory rates the impact as Important and requires a system reboot after applying the update. The update is available for various Red Hat Enterprise Linux 9 variants on x86_64 and ppc64le architectures.
