CVE-2024-38950Public exploitNetwork attack vector

Player crash via stale SDL texture dimensions

Published Jun 26, 2024 · Updated Aug 12, 2024

Heap buffer overflow in Struktur AG libde265 1.0.15 allows attackers to crash dec265 by opening a crafted H.265 bitstream. SDL_YUV_Display initializes its YV12 texture only once, then copies a later frame using changed dimensions without resizing the texture. A user or consuming workflow must open the crafted stream; the demonstrated consequence is an out-of-bounds read and application abort, not code execution.
