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

  - A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix,     Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a     dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this     pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block     device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without     user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug     events. This could lead to limited information disclosure or denial of service. (CVE-2026-13595)

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