CVE-2026-53145

A flaw was found in the Linux kernel's Direct Rendering Manager (DRM) Graphics Execution Manager (GEM) subsystem. A race condition exists within the `change_handle` ioctl between `gem_close` and `gem_change_handle` operations. This could lead to incorrect handling of graphics memory, potentially resulting in system instability or unexpected behavior. The `change_handle` ioctl has been temporarily disabled to mitigate this issue.
