Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security issue with the vblank irq in drm/msm/dpu...

PT-2024-26793

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the Linux kernel, where the fdcc clock is part of hdmi rx verification IP and should not be enabled for HDMI TX. However, if the clock is disabled before HDMI/LCD...

PT-2024-14632

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the addition of a mutex lock in the control vblank irq to synchronize vblank enable/disable operations happening from different threads, preventing race condition...

kernel: drm: Fix potential null-ptr-deref in drm_vblank_destroy_worker()

A flaw was found in the DRM subsystem in the Linux kernel. A NULL pointer dereference can be triggered due to a missing check, causing a system crash and resulting in a denial of service...

PT-2025-18544 · Linux +2 · Linux Kernel +2

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to the fixed version Description: A potential null pointer dereference issue has been identified in the Linux kernel, specifically in the drm vblank destroy worker function. This issue arises when drm vblank init...

SUSE CVE-2010-4078

The sisfbioctl function in drivers/video/sis/sismain.c in the Linux kernel before 2.6.36-rc6 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FBIOGETVBLANK ioctl call...

SUSE CVE-2010-4079

The ivtvfbioctl function in drivers/media/video/ivtv/ivtvfb.c in the Linux kernel before 2.6.36-rc8 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FBIOGETVBLANK ioctl call...

PT-2023-33867 · Linux · Linux Kernel

Name of the Vulnerable Software and Affected Versions: Linux Kernel versions prior to v6.0.16 Description: The issue is related to the drm/amd/display component, where it fails to wait for vblank during pipe programming. The actual impact and attack plausibility have not yet been proven...

PT-2025-37699

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw where an underflow may occur when using a display with a large vblank region and a low refresh rate. The issue is addressed by simplifying the calculatio...
