CVE-2026-43182: media: ccs: Avoid possible division by zero

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: 0.12% (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 32a21ed2ad743fe2d12af48e627089b921a032c2, 679f0b7b6a409750a25754c8833e268e5fdde742, 8ca7df18e7a58a0e5b0ed9eaaa34e16fc5cb9680.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 32a21ed2ad743fe2d12af48e627089b921a032c2, 679f0b7b6a409750a25754c8833e268e5fdde742, 8ca7df18e7a58a0e5b0ed9eaaa34e16fc5cb9680 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: ccs: Avoid possible division by zero Calculating maximum M for scaler configuration involves dividing by MIN_X_OUTPUT_SIZE limit register's value. Albeit the value is presumably non-zero, the driver was missing the check it in fact was. Fix this.

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.
