| CVE-2026-13595 Open CVE-2026-13595 in a new tab | 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. | Not affected | Medium | |
| CVE-2022-0563 Open CVE-2022-0563 in a new tab | A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. | Not affected | Low | |

| CVE-2026-78408 Open CVE-2026-78408 in a new tab | Util-linux: util-linux: nsenter --join-cgroup leaks root cgroup migration authority | Not affected | Unknown | |
| CVE-2026-78409 Open CVE-2026-78409 in a new tab | Util-linux: util-linux: x-mount.subdir detached-tree resolution can escape via intermediate symlinks | Not affected | Unknown | |
| CVE-2026-78410 Open CVE-2026-78410 in a new tab | Util-linux: util-linux: restricted bind mounts do not pin the source, allowing x-mount.owner/group/mode redirection | Not affected | Unknown |
