CVE-2021-47445
Last modified
CVE-2021-47445 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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"). EPSS estimates a 0.23% chance of exploitation in the next 30 days.
