CVE-2022-50287 Details
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)
A memory leak vulnerability has been identified in the Linux kernel's handling of BIOS data for Intel graphics. This issue arises in the function that generates pointers for the LFP (Low-Frequency Panel) data table. The vulnerability occurs when certain conditions related to the size and LVDS (Low-Voltage Differential Signaling) entries are met. In these cases, the function attempts to free a pointer that was not properly allocated, leading to potential memory leaks or undefined behavior. The vulnerability has been addressed by modifying the code to correctly manage memory allocation and deallocation.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. The specific commit addressing this issue can be found in the Linux kernel stable tree.
