Answer in brief
CVE-2023-52687 records a Critical severity (CVSS 9.8) vulnerability in crypto: safexcel - Add error handling for dma_map_sg() calls. 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 9.8. 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: crypto: safexcel - Add error handling for dma_map_sg() calls Macro dma_map_sg() may return 0 on error. This patch enables checks in case of the macro failure and ensures unmapping of previously mapped buffers with dma_unmap_sg(). Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.
