Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:21325-1 advisory.

 Changes in cryptsetup:

 - Fix for (bsc#1270254) to avoid undesired pinning of all volume keys (via the thread keyring) through the caller's credentials when the kernel opens a file. This is due to the refactoring in kernel commit a28d893eb327 (md: port block device access to file) that accidentally causes the caller's thread keyring to be kept alive long beyond the caller's lifetime, the kernel part is tracked in (bsc#1270252).

 * Add keyring key type. [b6fb6fc0]
 * Load volume keys in intermediary keyring linked in thread keyring. [413a3dd0]
 * Use unique intermediary keyring name per device. [04ef07a7]
 * Add regression tests. [bfcb0c38, bb5e8e9f, e6573494, aa214c09]

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
