CVE-2026-13595 is a heap use-after-free read in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers store a raw pointer to a parent partition entry located in a dynamically allocated array. If additional partition entries are subsequently added and the backing array is reallocated, the cached parent pointer becomes stale. Later dereference of that stale pointer results in a heap use-after-free read. The issue is reachable when libblkid parses a crafted block device image, including removable media or loop-mounted disk images. Because libblkid may be invoked automatically by udev/udisks as root during block-device hot-plug handling, exploitation can occur without user interaction beyond presenting the malicious image to the target system.
