medium Tenable Self-Hosted Container Security Plugin ID 475640

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: netfs: Fix uninitialized return value
in netfs_unbuffered_write() If preparation of the first subrequest fails, netfs_unbuffered_write() exits
its loop before ret is initialized. The empty-iterator check can do the same. For synchronous writes,
netfs_unbuffered_write_iter_locked() may then return an unrelated error instead of wreq->error. This is
reachable through CIFS if cifs_prepare_write() fails to reopen the file or obtain credits. Initialize ret
to 0 so the caller returns wreq->error if no data was written, or the number of bytes already written
otherwise. Found with Clang's -Wconditional-uninitialized. (CVE-2026-97610)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.106 or later.
