Linux · Linux Kernel · CVE-2022-49221
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A issue in the Linux kernel has been identified where the `dp panel` struct's `connector` is not assigned, leading to a NULL pointer dereference error. This occurs because the `connector` is stored in `msm dp` instead, and when running compliance testing, the `dp panel handle sink request()` function attempts to use the `connector`'s `real edid checksum` without a valid `edid` set. The problem arises during the DP CTS test case 4.2.2.6, where a valid EDID with a bad checksum is used, and the DP source is expected to return the correct checksum.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
