Red Hat Security Advisory: kernel-rt security update
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: tcp/dccp: Don't use timer_pending() in reqsk_queue_unlink(). (CVE-2024-50154) * kernel: net: ch9200: fix uninitialised access during mii_nway_restart (CVE-2025-38086) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The Red Hat kernel-rt security update fixes two vulnerabilities: CVE-2024-50154 addresses an issue in the TCP/DCCP networking code where timer_pending() was improperly used in reqsk_queue_unlink(), potentially leading to use-after-free conditions (CWE-416). CVE-2025-38086 resolves an uninitialized memory access in the ch9200 network driver during mii_nway_restart (CWE-908). These fixes are included in updated kernel-rt packages for Red Hat Enterprise Linux 8 Real Time variants. The advisory rates the impact as moderate and requires a system reboot to apply the update.
Potential Impact
The vulnerabilities could lead to instability or unintended behavior in the kernel's networking stack due to use-after-free and uninitialized memory access issues. The moderate severity rating indicates these are not critical but could affect system reliability or security if exploited. No known exploits in the wild have been reported.
Mitigation Recommendations
Red Hat has released updated kernel-rt packages that address these vulnerabilities. Users should apply the security update as detailed in the Red Hat advisory RHSA-2025:11456 and reboot affected systems to ensure the fixes take effect. Patch status is confirmed as available via this official update.
