CVE-2025-54957 is a memory-corruption vulnerability in Dolby Unified Decoder Core (UDC) versions 4.5 through 4.13 affecting processing of Dolby Digital Plus (DD+) bitstreams. When Evolution metadata from a malformed but parser-accepted DD+ bitstream is handled in the decoder logic associated with evo_priv.c, the decoder computes the length for a buffer write using arithmetic that can wrap around. This integer overflow causes the allocation size to become smaller than required. As a result, the subsequent bounds check for the write is rendered ineffective and attacker-controlled metadata can be written past the end of the allocated buffer, producing an out-of-bounds write. On affected Android deployments, the flaw is reachable through media decoding paths and has been described as potentially reachable in zero-click scenarios where audio content is automatically processed for transcription or previewing.
