high Tenable Cloud Security Plugin ID 469193

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: uio: Fix stale info pointer in failed
registration path After device_add(), the UIO device is visible to userspace and /dev/uioX can be opened.
If a later setup step fails, __uio_register_device() unwinds the device but leaves idev->info pointing at
the caller-owned struct uio_info. That is unsafe when an opener races with the failed registration path.
The open file keeps a reference to the uio_device, while the caller sees registration failure and may free
its struct uio_info. Later file operations can then follow idev->info and dereference freed memory. Handle
post-device_add() failures like unregister: remove UIO attributes while the info pointer is still valid,
then clear idev->info under info_lock and wake existing waiters/async users before removing the device and
minor. This makes already-open file descriptors observe the same "device gone" state as normal
uio_unregister_device(). (CVE-2026-93054)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
