GSD-2021-47057

Vulnerability from gsd - Updated: 2024-03-01 06:04
Details
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")
