CVE-2023-53239 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Add check for kzalloc As kzalloc may fail and return NULL pointer, it should be better to check the return value in order to avoid the NULL pointer dereference. Patchwork: https://patchwork.freedesktop.org/patch/514154/
A vulnerability allowing a NULL pointer dereference has been identified in the Linux kernel's DRM MSM MDP5 component. This issue arises because the memory allocation function 'kzalloc' may fail, leading to a NULL pointer being used without proper validation. The vulnerability has been addressed by adding a check for the return value of 'kzalloc' to ensure it does not result in a NULL pointer dereference.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the official Linux kernel website.
