CVE-2024-49860: ACPI: sysfs: validate return type of _STR method

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.25% (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 0cdfb9178a3bba843c95c2117c82c15f1a64b9ce, 2364b6af90c6b6d8a4783e0d3481ca80af699554, 4b081991c4363e072e1748efed0bbec8a77daba5; azl3 kernel 6.6.51.1-5 on Azure Linux 3.0 6.6.56.1-5; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.56.1-5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0cdfb9178a3bba843c95c2117c82c15f1a64b9ce, 2364b6af90c6b6d8a4783e0d3481ca80af699554, 4b081991c4363e072e1748efed0bbec8a77daba5; azl3 kernel 6.6.51.1-5 on Azure Linux 3.0 6.6.56.1-5; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.56.1-5 or later.

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.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

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