CVE ID :CVE-2026-53378<\/p>\n

Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/colorop: Fix blob property reference tracking in state lifecycle<\/p>\n
The colorop state blob property handling had memory leaks during state
\nduplication, destruction, and reset operations. The implementation
\nfailed to follow the established pattern from drm_crtc’s handling of
\nDEGAMMA\/GAMMA blob properties.<\/p>\n
Issues fixed:
\n– drm_colorop_atomic_destroy_state() was freeing state memory without
\n releasing the blob reference, causing a leak
\n– drm_colorop_reset() was directly freeing old state with kfree()
\n instead of properly destroying it, leaking blob references
\n– drm_colorop_cleanup() had duplicate blob cleanup code<\/p>\n
Changes:
\n– Add __drm_atomic_helper_colorop_destroy_state() helper to properly
\n release blob references before freeing state memory
\n– Update drm_colorop_atomic_destroy_state() to call the helper
\n– Fix drm_colorop_reset() to use drm_colorop_atomic_destroy_state()
\n for proper cleanup of old state
\n– Simplify drm_colorop_cleanup() to use the common destruction path<\/p>\n
This matches the well-tested pattern used by drm_crtc since 2016 and
\nensures proper reference counting throughout the state lifecycle.<\/p>\n
