{"cve":"CVE-2026-13595","nvd":{"published":"2026-06-29T09:16:28.303","modified":"2026-10-30T14:17:05.323","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:H","score":5.3},"cwes":["CWE-416"],"references":["https://access.redhat.com/errata/RHSA-2026:26573","https://access.redhat.com/security/cve/CVE-2026-13595","https://bugzilla.redhat.com/show_bug.cgi?id=2494101","https://github.com/util-linux/util-linux/commit/c0186f14fbdb02f64c8e0ba701ce727ea764ff4c"],"products":["kernel:util-linux","redhat:enterprise_linux","redhat:hardened_images","redhat:openshift_container_platform"],"source":"nvd","synced_at":"2026-10-30T14:33:49.494135507+00:00"},"epss":{"cve":"CVE-2026-13595","score":0.00144,"percentile":0.0372,"date":"2026-10-30"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
