Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the drm/i915/bios module, specifically within the generate lfp data ptrs function. The issue occurs when size is not equal to 0 or ptrs->lvds entries is not equal to 3, leading to an attempt to free memory that was not allocated using kzmalloc(), but obtained through a pointer offset operation. This can result in memory leaks or undefined behavior. The fix involves replacing the arguments of kfree() with ptrs block.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
