Change History

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.
