Red Hat Security Advisory: kernel security update
The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: HID: core: Harden s32ton() against conversion to 0 bits (CVE-2025-38556) * kernel: wifi: ath12k: Decrement TID on RX peer frag setup error handling (CVE-2025-39761) * kernel: ALSA: usb-audio: Validate UAC3 cluster segment descriptors (CVE-2025-39757) 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 advisory covers three kernel vulnerabilities in Red Hat Enterprise Linux 10. CVE-2025-38556 involves hardening the HID core function s32ton() to prevent conversion to zero bits, addressing a potential memory or data handling issue. CVE-2025-39761 fixes the ath12k wifi driver to properly decrement TID on RX peer fragment setup errors, improving error handling. CVE-2025-39757 enhances validation of UAC3 cluster segment descriptors in the ALSA usb-audio driver to prevent malformed descriptor issues. Red Hat has released updated kernel packages containing these fixes, requiring system reboot for activation. The advisory rates these issues as moderate in severity and no active exploitation has been reported.
Potential Impact
The vulnerabilities affect the Linux kernel core and specific drivers (HID, wifi ath12k, ALSA usb-audio) in Red Hat Enterprise Linux 10. They could potentially lead to improper data handling or error processing within kernel components, which might affect system stability or security. However, no known exploits in the wild have been reported, and Red Hat rates the overall impact as moderate.
Mitigation Recommendations
Red Hat has released updated kernel packages for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply the official kernel update as provided in advisory RHSA-2025:17776 and reboot their systems to ensure the fixes take effect. For detailed update instructions, refer to https://access.redhat.com/articles/11258. There are no indications that additional mitigations are required beyond applying the official update and rebooting.
