https://notcve.org/view.php?id=CVE-2023-52687
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. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: safexcel - Añadir manejo de errores para llamadas a dma_map_sg() La macro dma_map_sg() puede devolver 0 en caso de error. Este parche permite realizar comprobaciones en caso de fallo de la macro y garantiza la eliminación de la asignación de búferes previamente asignados con dma_unmap_sg(). Encontrado por el Centro de verificación de Linux (linuxtesting.org) con la herramienta de análisis estático SVACE. • https://git.kernel.org/stable/c/49186a7d9e46ff132a0ed9b721ad6b6a58dba6c1 https://git.kernel.org/stable/c/4c0ac81a172a69a7733290915276672787e904ec https://git.kernel.org/stable/c/8084b788c2fb1260f7d44c032d5124680b20d2b2 https://git.kernel.org/stable/c/fc0b785802b856566df3ac943e38a072557001c4 https://git.kernel.org/stable/c/87e02063d07708cac5bfe9fd3a6a242898758ac8 •
