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

  - bpf: Reject MEM_ALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for     accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTR_TO_BTF_ID     | MEM_ALLOC values point to objects allocated with the static BTF type size. When walking a MEM_ALLOC     object, reject the access before applying the flexible-array relaxation if the access range extends past     the struct size. Apply the same policy to struct ID matching so kfunc and kptr type checks do not walk     past the allocated object bounds either. (CVE-2026-93148)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3390 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    sctp: validate cookie AUTH state before use (CVE-2026-74752)

    In the Linux kernel, the following vulnerability has been resolved:

    bpf: Reject MEM_ALLOC BTF accesses past object bounds (CVE-2026-93148)

    In the Linux kernel, the following vulnerability has been resolved:

    smb: client: reject out-of-bounds DataOffset in CIFSSMBRead() (CVE-2026-97563)

    In the Linux kernel, the following vulnerability has been resolved:

    bpf: Preserve inner map identity in callback frames (CVE-2026-98033)

    In the Linux kernel, the following vulnerability has been resolved:

    smb: client: validate absolute native symlink targets before NT fixups (CVE-2026-98318)

    In the Linux kernel, the following vulnerability has been resolved:

    bpf: Use array_map_meta_equal for percpu array inner map replacement (CVE-2026-98376)

    In the Linux kernel, the following vulnerability has been resolved:

    KVM: SVM: Preserve TLB control (i.e. pending TLB flush) on failed VMRUN (CVE-2026-98715)

    futex: Fix private hash use-after-free on resize (CVE-2026-98788)

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

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