CVE-2026-72171: mtd: slram: remove failed entries from the device list

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 200b8bc5b6065b02f3775cf131f14b8e1156a00a, 2fd0cbbb34447ccddab67a2a638a07c6d94cae7a, 36f1648644d769c496a8e47e53603e863e358d73.

Low priority for now. Upgrade to Linux Linux 200b8bc5b6065b02f3775cf131f14b8e1156a00a, 2fd0cbbb34447ccddab67a2a638a07c6d94cae7a, 36f1648644d769c496a8e47e53603e863e358d73 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: mtd: slram: remove failed entries from the device list register_device() links a new slram_mtdlist entry before allocating all of the state needed by the entry. If a later allocation, memremap(), or mtd_device_register() fails, the partially initialized entry remains on the global list. A later cleanup can then dereference or free invalid state from that failed entry. Unwind the partially initialized entry and clear the list tail on each failure path after the entry has been linked.

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.

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.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

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.
