Description OSIDB Bzimport 2026-08-15 06:31:32 UTC

In the Linux kernel, the following vulnerability has been resolved:

crypto: marvell/octeontx - fix DMA cleanup using wrong loop index

The sg_cleanup path used list[i] instead of list[j] when unmapping DMA
buffers, leaking successfully mapped entries and repeatedly unmapping
the failed one.
