From: Daniel Turull <[email protected]> The RAR5 double-free in init_unpack() is a regression introduced upstream by commit 620bdafa on 2026-05-16 and existed only on the git master branch until it was fixed by PR #3071 (commit 1c914cdf) on 2026-05-24. It was never part of an upstream release.
The upstream release tarballs (3.6.x/3.7.x/3.8.6) use the older init_unpack() with unchecked calloc and no early-return path, so the freed window_buf/filtered_buf pointers are never left dangling and the double-free cannot occur.
