CVE-2026-74280: crypto: marvell/octeontx - fix DMA cleanup using wrong loop index
In the Linux kernel, the following vulnerability has been resolved:
crypto: marvell/octeontx - fix DMA cleanup using wrong loop index
The sgcleanup path used list[i] instead of list[j] when unmapping DMA buffers, leaking successfully mapped entries and repeatedly unmapping the failed one.
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Upgrade the Linux kernel to a version where the sg_cleanup DMA unmap bug (“fix DMA cleanup using wrong loop index”) is resolved so the wrong loop index (list[i] vs list[j]) no longer causes leaked successfully mapped entries and repeated unmapping.
