CVE-2023-45678 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of buffer write in `start_decoder` because at maximum `m->submaps` can be 16 but `submap_floor` and `submap_residue` are declared as arrays of 15 elements. EPSS estimates a 0.73% chance of exploitation in the next 30 days.
