CVE-2026-5318
Status: AnalyzedLow (2.1)—
A weakness has been identified in LibRaw up to 0.22.0. This impacts the function HuffTable::initval of the file src/decompressors/losslessjpeg.cpp of the component JPEG DHT Parser. This manipulation of the argument bits[] causes out-of-bounds write. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 0.22.1 will fix this issue. Patch name: a6734e867b19d75367c05f872ac26322464e3995. It is advisable to upgrade the affected component.

- Base score: 2.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.78%
- Percentile among all scored CVEs: 55
- Score date: 10/3/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
