CVE-2026-58107: Ericsson Codechecker

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

CodeChecker's massStoreRun processing path performs one-shot decompression of attacker-controlled, Base64-encoded zlib data without enforcing a maximum decompressed size. An authenticated user with permission to store analysis runs can submit a highly compressed payload that expands to a significantly larger byte sequence. Because the entire decompressed output is materialized in memory before being written to a temporary file, a sufficiently large payload may exhaust process or host memory and consume substantial disk space, resulting in denial of service.

Affected products

  • Ericsson Codechecker: before 6.28.3 (fixed in 6.28.3)
