Name of the Vulnerable Software and Affected Versions util-linux versions prior to 2.22.2

Description The issue concerns multiple vulnerabilities in the util-linux package that can be exploited locally, potentially leading to breaches of confidentiality, integrity, and availability of protected information. In util-linux 2.19 and earlier, the mount function does not remove the /etc/mtab~ lock file after a failed attempt to add a mount entry, which has an unspecified impact and can be exploited through local attack vectors.

Recommendations For util-linux versions prior to 2.22.2, update to version 2.22.2 or later to resolve the issue. As a temporary workaround, consider manually removing the /etc/mtab~ lock file after failed mount attempts to minimize the risk of exploitation.
