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)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"util-linux","purl":"pkg:rpm/openEuler/util-linux&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.35.2-30.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["libblkid-2.35.2-30.oe2003sp4.aarch64.rpm","libfdisk-2.35.2-30.oe2003sp4.aarch64.rpm","libmount-2.35.2-30.oe2003sp4.aarch64.rpm","libsmartcols-2.35.2-30.oe2003sp4.aarch64.rpm","libuuid-2.35.2-30.oe2003sp4.aarch64.rpm","python-libmount-2.35.2-30.oe2003sp4.aarch64.rpm","util-linux-2.35.2-30.oe2003sp4.aarch64.rpm","util-linux-debuginfo-2.35.2-30.oe2003sp4.aarch64.rpm","util-linux-debugsource-2.35.2-30.oe2003sp4.aarch64.rpm","util-linux-devel-2.35.2-30.oe2003sp4.aarch64.rpm","util-linux-user-2.35.2-30.oe2003sp4.aarch64.rpm","uuidd-2.35.2-30.oe2003sp4.aarch64.rpm"],"noarch":["util-linux-help-2.35.2-30.oe2003sp4.noarch.rpm"],"src":["util-linux-2.35.2-30.oe2003sp4.src.rpm"],"x86_64":["libblkid-2.35.2-30.oe2003sp4.x86_64.rpm","libfdisk-2.35.2-30.oe2003sp4.x86_64.rpm","libmount-2.35.2-30.oe2003sp4.x86_64.rpm","libsmartcols-2.35.2-30.oe2003sp4.x86_64.rpm","libuuid-2.35.2-30.oe2003sp4.x86_64.rpm","python-libmount-2.35.2-30.oe2003sp4.x86_64.rpm","util-linux-2.35.2-30.oe2003sp4.x86_64.rpm","util-linux-debuginfo-2.35.2-30.oe2003sp4.x86_64.rpm","util-linux-debugsource-2.35.2-30.oe2003sp4.x86_64.rpm","util-linux-devel-2.35.2-30.oe2003sp4.x86_64.rpm","util-linux-user-2.35.2-30.oe2003sp4.x86_64.rpm","uuidd-2.35.2-30.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2883"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13595"}],"database_specific":{"severity":"Medium"}}
