EulerOS 2.0 SP12 : util-linux (EulerOS-SA-2026-3317)

medium Nessus Plugin ID 343697

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the util-linux packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 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)

Tenable has extracted the preceding description block directly from the EulerOS util-linux security advisory.

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

Solution

Update the affected util-linux packages.
