NULL Pointer Dereference vulnerability in the ALS audio decoder of the FFmpeg multimedia framework. The flaw lies in the decode_init() function, where memory allocation results (e.g., larray, nbits, raw_mantissa[c]) are not validated before use. If a crafted ALS file causes allocation functions like av_malloc_array() or av_calloc() to fail, the code may dereference NULL pointers, leading to application crashes. This issue can be triggered remotely without any authentication, resulting in a denial-of-service scenario for any application using FFmpeg for ALS decoding.
