In the Linux kernel, the following vulnerability has been resolved: keys: make keyring key-chunk byte order agree with keyring_diff_objects() keyring_get_key_chunk() loads description bytes into the index chunk low address first, while keyring_diff_objects() numbers the first differing bit from the low end and folds the absolute byte index into the level without removing the inline-prefix offset the level already carries. The two disagree on byte order and bit position, so the array can be told two keys first differ at a bit that does not differ in the chunk the walker uses, letting crafted descriptions collide into one node. Load the chunk in the order keyring_diff_objects() assumes and drop the inline-prefix length when folding the byte index into the level. This only changes the in-memory ordering used to place keys within a keyring; add, search and read of non-colliding keys are unaffected.

The remote Oracle Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-500249 advisory.

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

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.105-1.

    We recommend that you upgrade your linux packages.

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

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

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.

  - keys: make keyring key-chunk byte order agree with keyring_diff_objects() keyring_get_key_chunk() loads     description bytes into the index chunk low address first, while keyring_diff_objects() numbers the first     differing bit from the low end and folds the absolute byte index into the level without removing the     inline-prefix offset the level already carries. The two disagree on byte order and bit position, so the     array can be told two keys first differ at a bit that does not differ in the chunk the walker uses,     letting crafted descriptions collide into one node. Load the chunk in the order keyring_diff_objects()     assumes and drop the inline-prefix length when folding the byte index into the level. This only changes     the in-memory ordering used to place keys within a keyring; add, search and read of non-colliding keys are     unaffected. (CVE-2026-74566)

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

An update of the linux package has been released.
