CVE-2026-110599
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
L-SMASH through 2.14.5 contains a double free vulnerability in hevc_setup_first_summary() and h264_setup_first_summary() in importer/nalu_imp.c that frees borrowed codec-specific objects on error paths. Attackers can supply a crafted Annex-B elementary stream lacking a parseable SPS to lsmash_read_file() or the boxdumper, remuxer, or muxer tools, causing use-after-free, heap corruption, and crashes.
Risk Assessment
Processing a malicious media file can lead to memory corruption and potential code execution in the context of the application processing the file. This can result in system compromise or service crash.
Recommendation
Update L-SMASH to a version later than 2.14.5. Avoid processing untrusted media files until the fix is deployed.
