Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description Memory leaks occur in the drm/colorop state blob property handling during state duplication, destruction, and reset operations. The issue stems from a failure to follow established reference tracking patterns, specifically within the following functions:
  • drm colorop atomic destroy state() frees state memory without releasing the blob reference.
  • drm colorop reset() uses kfree() to free old state instead of properly destroying it, leading to leaked blob references.
  • drm colorop cleanup() contains duplicate blob cleanup code.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
