In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Fix use after free and double free on init error If the driver initialization fails, the vkms_exit() function might access an uninitialized or freed default_config pointer and it might double free it. Fix both possible errors by initializing default_config only when the driver initialization succeeded.
AI Analysis
Technical Summary
This Red Hat security advisory addresses several vulnerabilities in the Linux kernel packages, which form the core of the operating system. The fixed issues include CVE-2025-22097 (use after free and double free in drm/vkms), CVE-2025-37803 (buffer size overflow in udmabuf creation), CVE-2025-38350 (notification handling in net/sched), and CVE-2025-38449 (reference acquisition on GEM handles for framebuffers). These vulnerabilities relate to memory management errors and notification handling within kernel subsystems. The advisory applies to Red Hat Enterprise Linux 10 and its extended update support versions across multiple hardware architectures. Red Hat rates the security impact as Important and provides updated kernel packages that require a reboot to apply.
Potential Impact
The vulnerabilities fixed involve memory safety issues such as use-after-free, double free, and buffer overflow, which can lead to system instability or potential escalation of privileges if exploited. The notification handling issue may affect kernel scheduling behavior. These issues impact the core Linux kernel on Red Hat Enterprise Linux 10 systems. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated kernel packages that address these vulnerabilities. Users should apply the available kernel update for Red Hat Enterprise Linux 10 as detailed in the advisory (RHSA-2025:15447) and reboot the system to activate the fixes. This is the official and recommended remediation. Patch status is confirmed as fixed in the updated kernel packages provided by Red Hat.
