Technical Analysis

This advisory covers two race condition vulnerabilities in the Red Hat kernel-rt packages for Red Hat Enterprise Linux 8. CVE-2024-53088 addresses a race condition in the i40e network driver by adding a filter's intermediate synchronization state. CVE-2024-53122 addresses a race condition in multipath TCP (mptcp) subflow creation within the mptcp_rcv_space_adjust function. Both vulnerabilities could lead to potential synchronization issues in kernel operations. Red Hat has released updated kernel-rt packages to fix these issues, and a reboot is required to apply the updates.

Potential Impact

The vulnerabilities involve race conditions in kernel components, which could lead to unpredictable behavior or potential denial of service in systems using the affected kernel-rt packages. The Real Time Linux Kernel is critical for systems requiring precise timing and determinism, so these issues could impact system stability or reliability if exploited. No known exploits in the wild have been reported at this time.

Mitigation Recommendations

Red Hat has released updated kernel-rt packages that address these vulnerabilities. Users should apply the security update as detailed in Red Hat's advisory (RHSA-2025:0066) and reboot affected systems to ensure the fixes take effect. Patch status is confirmed by the vendor advisory. No additional mitigation steps are indicated beyond applying the official update and rebooting.
