In the Linux kernel, the following vulnerability has been resolved: ext4: verify orphan file size is not too big In principle orphan file can be arbitrarily large. However orphan replay needs to traverse it all and we also pin all its buffers in memory. Thus filesystems with absurdly large orphan files can lead to big amounts of memory consumed. Limit orphan file size to a sane value and also use kvmalloc() for allocating array of block descriptor structures to avoid large order allocations for sane but large orphan files.

    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

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

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.

  - ext4: verify orphan file size is not too big In principle orphan file can be arbitrarily large. However     orphan replay needs to traverse it all and we also pin all its buffers in memory. Thus filesystems with     absurdly large orphan files can lead to big amounts of memory consumed. Limit orphan file size to a sane     value and also use kvmalloc() for allocating array of block descriptor structures to avoid large order     allocations for sane but large orphan files. (CVE-2025-40179)

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