CVE-2026-119738
The VobSub subtitle decoder libsubvob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an infinite loop vulnerability in getvobspu() that allows unauthenticated network attackers or local users loading malicious files to trigger an unreachable loop exit condition via mismatched length fields. Attackers can send crafted AMLU data blocks over the unauthenticated tcp/10100 listener or via a malicious VobSub (.sub) file to cause the subtitle decode thread to spin at 100% CPU indefinitely, resulting in denial of service.
