medium Tenable Cloud Security Plugin ID 451041

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: fs/smb: Fix inconsistent refcnt update
A possible inconsistent update of refcount was identified in `smb2_compound_op`. Such inconsistent update
could lead to possible resource leaks. Why it is a possible bug: 1. In the comment section of the
function, it clearly states that the reference to `cfile` should be dropped after calling this function.
2. Every control flow path would check and drop the reference to `cfile`, except the patched one. 3.
Existing callers would not handle refcount update of `cfile` if -ENOMEM is returned. To fix the bug, an
extra goto label "out" is added, to make sure that the cleanup logic would always be respected. As the
problem is caused by the allocation failure of `vars`, the cleanup logic between label "finished" and
"out" can be safely ignored. According to the definition of function `is_replayable_error`, the error code
of "-ENOMEM" is not recoverable. Therefore, the replay logic also gets ignored. (CVE-2025-39819)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.448.50 or later.
