CVE-2026-68084: staging: vme_user: fix location monitor leak in tsi148 bridge

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

Description
===========

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

staging: vme_user: fix location monitor leak in tsi148 bridge

tsi148_probe() allocates a location monitor resource and links it into
tsi148_bridge->lm_resources. The probe error path frees this list, but
tsi148_remove() only frees the dma, slave and master resource lists, so
the location monitor resource is leaked on device unbind or module
unload.

Free the lm_resources list in tsi148_remove() as well, before
tsi148_bridge is freed.

The Linux kernel CVE team has assigned CVE-2026-68084 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:
