# CVE-2026-72088: scsi: hpsa: Fix DMA mapping leak on IOACCEL2 reset path

Status: published. Published: 2026-08-15. Updated: 2026-11-06.

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

scsi: hpsa: Fix DMA mapping leak on IOACCEL2 reset path

If phys_disk->in_reset is set, the function returns directly without
undoing the resources acquired for the command. Add the missing error
cleanup by unmapping the IOACCEL2 SG chain block when needed, unmapping
the SCSI command, and dropping the outstanding IOACCEL command count
before returning.
