Vulnerability from fkie_nvd - Published: 2024-05-22 07:15 - Updated: 2025-01-14 16:28
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix null pointer dereference on pointer edp The initialization of pointer dev dereferences pointer edp before edp is null checked, so there is a potential null pointer deference issue. Fix this by only dereferencing edp after edp has been null checked. Addresses-Coverity: ("Dereference before null check")
