medium Tenable Cloud Security Plugin ID 467374

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: drivers/base/memory: set mem->altmap
after successful device registration If __add_memory_block() fails at xa_store() (under memory pressure
for example), device_unregister() is called, which eventually triggers memory_block_release() with
mem->altmap still set, causing a WARN_ON(mem->altmap). This was triggered by modifying virtio-mem driver.
Fix this by delaying the assignment of mem->altmap until after __add_memory_block() has succeeded.
(CVE-2026-64244)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.36 or later.
