Subject: CVE-2026-72088: scsi: hpsa: Fix DMA mapping leak on IOACCEL2 reset path
Date: Sat, 15 Aug 2026 15:02:47 +0900 [thread overview]
Message-ID: <2026081522-CVE-2026-72088-cc25@gregkh> (raw)
From: Greg Kroah-Hartman <gregkh@kernel.org>
Description
===========
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.
The Linux kernel CVE team has assigned CVE-2026-72088 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
