This Red Hat security advisory (RHSA-2024:1532) fixes two kernel vulnerabilities in Red Hat Enterprise Linux 9.2 Extended Update Support. CVE-2024-0565 is a remote code execution vulnerability caused by improper input validation in the CIFS filesystem decryption function receive_encrypted_standard. CVE-2024-26602 mitigates the ability to excessively hammer the sys_membarrier system call, which could affect scheduler stability. The advisory also includes multiple bug fixes and updates the kernel to version 5.14.0-284.59.1.el9_2. The update requires a system reboot to take effect.

The CVE-2024-0565 vulnerability could allow remote code execution via the CIFS filesystem client due to improper input validation during decryption. CVE-2024-26602 reduces the risk of denial-of-service or performance degradation caused by excessive calls to sys_membarrier. Both vulnerabilities affect the kernel, the core of the operating system, potentially impacting system security and stability if unpatched.

Red Hat has released an official security update for Red Hat Enterprise Linux 9.2 Extended Update Support that addresses these vulnerabilities. Users should apply the kernel update as detailed in the Red Hat advisory (https://access.redhat.com/articles/11258) and reboot their systems to activate the fixes. No additional mitigation steps are indicated beyond applying the official patch and rebooting.
