CVE-2021-47057
In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ss - Fix memory leak of object d when dma_iv fails to map In the case where the dma_iv mapping fails, the return error path leaks the memory allocated to object d.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ss - Fix memory leak of object d when dma_iv fails to map In the case where the dma_iv mapping fails, the return error path leaks the memory allocated to object d. Fix this by adding a new error return label and jumping to this to ensure d is free'd before the return. Addresses-Coverity: ("Resource leak")
