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.<\/p>\n<p>  Severity: 6.8 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-13595 Published : June 29, 2026, 8:06 a.m. | 1\u00a0hour, 39\u00a0minutes ago Description :A flaw was found in the libblkid library of util-linux.
