CVE-2022-48434: Ffmpeg

High severity, CVSS 8.1. EPSS: 1.5% chance of exploitation in the next 30 days.

libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).

Affected products

• Ffmpeg Ffmpeg: before 5.1.2 (fixed in 5.1.2)
