CVE-2026-52791 fuse-overlayfs release-1.x preserves SUID/SGID bits after truncate/open(O_TRUNC)

fuse-overlayfs is an implementation of overlayfs in FUSE for rootless containers. Prior to 1.17, the release-1.x C branch preserves SUID and SGID mode bits in main.c during openOTRUNC and truncate handling on a copied-up file, allowing a low-privileged process to leave the upper-layer file with...

CVE-2026-52791

Fuse-overlayfs (overlayfs in FUSE for rootless containers) before version 1.17 on the release-1.x C branch preserves SUID/SGID mode bits in main.c during open(O_TRUNC) and truncate handling on a copied-up file. This may allow a low-privilege process to leave the upper-layer file with mode 4777. T...

CVE-2026-47261

Wasmtime is a runtime for WebAssembly. In versions prior to 24.0.9, 36.0.10, and 44.0.2, when a filesystem preopen is given DirPerms::all and FilePerms::READ without FilePerms::WRITE, this access control mechanism can be bypassed via the wasip2 descriptor.open-at or wasip1 pathopen interfaces by...
