In the Linux kernel, the following vulnerability has been resolved: ipmi: Rework user message limit handling The limit on the number of user messages had a number of issues, improper counting in some cases and a use after free. Restructure how this is all done to handle more in the receive message allocation routine, so all refcouting and user message limit counts are done in that routine. It's a lot cleaner and safer.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     6.1.158-1~deb11u1.  This version additionally includes many more bug     fixes from stable updates 6.1.154-6.1.158.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ipmi: Rework user message limit handling The limit on the number of user messages had a number of issues,     improper counting in some cases and a use after free. Restructure how this is all done to handle more in     the receive message allocation routine, so all refcouting and user message limit counts are done in that     routine. It's a lot cleaner and safer. (CVE-2025-40202)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.
