CVE-2022-48749
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: invalid parameter check in dpu_setup_dspp_pcc The function performs a check on the "ctx" input parameter, however, it is used before the check.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
