Red Hat Security Advisory: kernel security update
This advisory addresses multiple moderate-severity vulnerabilities in the Linux kernel packages used by Red Hat Enterprise Linux 9 and related variants. The fixes cover issues including improper deinitialization in the ice driver, potential memory corruption in the scheduler, hex dump handling in the ibmvnic driver, and off-by-one and extended attribute handling errors in the ext4 filesystem code. These vulnerabilities could lead to memory corruption or other kernel-level faults. Red Hat has released updated kernel packages to resolve these issues, and a system reboot is required to apply the updates.
