Summary
In the Linux kernel Marvell OcteonTX crypto driver, the DMA cleanup path used the wrong loop index, leaking mapped entries and repeatedly unmapping the failed one.
Risk Assessment
DMA memory management errors can lead to memory leaks or malfunction of cryptographic hardware, potentially affecting data integrity.
Recommendation
Apply the Linux kernel update that fixes the indexing in the sg_cleanup function.
Original NVD description (English source)
