CVE-2026-72106: dm-ioctl: fix a possible overflow in list_version_get_info

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 29536a9ff146d9bbd618959857ed2e691cda1d21, 3cba74d3fb2c1890ffae019301227d1366f74907, 76c6f845dc0c614304a6e6ee619b552f97cf24b3.

Low priority for now. Upgrade to Linux Linux 29536a9ff146d9bbd618959857ed2e691cda1d21, 3cba74d3fb2c1890ffae019301227d1366f74907, 76c6f845dc0c614304a6e6ee619b552f97cf24b3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: dm-ioctl: fix a possible overflow in list_version_get_info sizeof(tt->version) is 12 bytes, but the code writes 16 bytes into the output buffer - info->vers->version[0], info->vers->version[1], info->vers->version[2] and info->vers->next. This can cause buffer overflow. Fix this buffer overflow by replacing "sizeof(tt->version)" with "sizeof(struct dm_target_versions)".

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
