CVE-2024-35813: mmc: core: Avoid negative index with array access
Noroxi assessment
Priority: Monitor (action score 22/100)
- 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: 0.24% (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 064db53f9023a2d5877a2d12de6bc27995f6ca56, 2b539c88940e22494da80a93ee1c5a28bbad10f6, 4466677dcabe2d70de6aa3d4bd4a4fafa94a71f2.
- Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.
Low priority for now. Upgrade to Linux Linux 064db53f9023a2d5877a2d12de6bc27995f6ca56, 2b539c88940e22494da80a93ee1c5a28bbad10f6, 4466677dcabe2d70de6aa3d4bd4a4fafa94a71f2 or later.

In the Linux kernel, the following vulnerability has been resolved: mmc: core: Avoid negative index with array access Commit 4d0c8d0aef63 ("mmc: core: Use mrq.sbc in close-ended ffu") assigns prev_idata = idatas[i - 1], but doesn't check that the iterator i is greater than zero. Let's fix this by adding a check.

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.
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 researchersFinders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.
No credits in the CNA record.
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.
