Answer in brief
CVE-2022-50393 records a High severity (CVSS 7.8) vulnerability in drm/amdgpu: SDMA update use unlocked iterator. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: SDMA update use unlocked iterator SDMA update page table may be called from unlocked context, this generate below warning. Use unlocked iterator to handle this case.
