Echo: linux: security update to 6.1.135-1

medium Tenable Self-Hosted Container Security Plugin ID 459564

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: avoid
 unregistering devlink regions which were never registered Russell King reports that a system with
 mv88e6xxx dereferences a NULL pointer when unbinding this driver:
 https://lore.kernel.org/netdev/[email protected]/ The crash seems to be in
 devlink_region_destroy(), which is not NULL tolerant but is given a NULL devlink global region pointer. At
 least on some chips, some devlink regions are conditionally registered since the blamed commit, see
 mv88e6xxx_setup_devlink_regions_global(): if (cond && !cond(chip)) continue; These are
 MV88E6XXX_REGION_STU and MV88E6XXX_REGION_PVT. If the chip does not have an STU or PVT, it should crash
 like this. To fix the issue, avoid unregistering those regions which are NULL, i.e. were skipped at
 mv88e6xxx_setup_devlink_regions_global() time. (CVE-2025-37787)

Solution

Update the linux library and its related packages to version 6.1.135-1 or later.
