CVE-2022-50287

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