CVE-2026-53401

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.1.3

Description A race condition exists in the omap2 framebuffer driver within the omapfb mmap() function and the OMAPFB SETUP PLANE ioctl. The fb mmap() entry point holds the mm lock but not the fb info->lock, while OMAPFB SETUP PLANE holds the fb info->lock but not the mm lock, allowing concurrent execution. This can lead to a use-after-free scenario where a user-space mapping is created for physical memory that has been freed because the map count was incremented for an old region reference while the mapping was based on a new region.

Recommendations Update to version 7.1.3.
