Description
In the Linux kernel, the following vulnerability has been resolved: drm/i915/bios: fix a memory leak in generate_lfp_data_ptrs When (size != 0 || ptrs->lvds_ entries != 3), the program tries to free() the ptrs. However, the ptrs is not created by calling kzmalloc(), but is obtained by pointer offset operation. This may lead to memory leaks or undefined behavior. Fix this by replacing the arguments of kfree() with ptrs_block. (cherry picked from commit 7674cd0b7d28b952151c3df26bbfa7e07eb2b4ec)

Executive Summary

This vulnerability is a memory leak in the Linux kernel's drm/i915/bios component. It occurs because the program attempts to free a pointer (ptrs) that was not allocated with kzmalloc(), but instead obtained via pointer offset operations. This incorrect free operation can lead to memory leaks or undefined behavior. The fix involved changing the argument to kfree() to use ptrs_block instead of ptrs.

Impact Analysis

This vulnerability can cause memory leaks or undefined behavior in the Linux kernel, which may degrade system performance or stability over time. In some cases, undefined behavior could potentially lead to crashes or other unpredictable system issues.
