GHSA-FR26-JJHM-638C pyLoad: Tar extraction creates device nodes and FIFOs (member types not filtered; tarfile extractall without filter=)

Summary UnTar.safeextractall — the hardening added for GHSA-mvwx-582f-56r7 — validates member names and symlink/hardlink targets, but never checks member types, and calls tarfile.extractall without a filter=. On Python : names/links only raise ArchiveError... tar.extractallpath, members,...

CVE-2026-47766

CVE-2026-47766 affects crun prior to version 1.28. When an OCI bundle uses a symlink for rootfs/dev and the bundle omits mounting /dev, crun may follow the symlink and create default device nodes and stdio symlinks at the symlink target outside the container rootfs. In a local rootful crun replay...

CVE-2026-47766

crun is an open source OCI Container Runtime fully written in C. Prior to version 1.28, crun's default device setup opens the container rootfs "/dev" directory without "ONOFOLLOW". If an OCI bundle contains "rootfs/dev" as a symlink and the bundle configuration does not mount "/dev", crun follows...

mknod: Device nodes created mislabeled on SELinux, with broken cleanup (remove_dir on a node)

uutils calls mknod before setting the SELinux context GNU uses setfscreatecon first, labeling atomically. If setselinuxsecuritycontext fails, cleanup uses std::fs::removedir, which cannot remove device nodes or FIFOs, leaving the mislabeled node behind. Impact: on SELinux-enforcing systems the no...

GHSA-8VRF-R662-2W2V cp: -R reads device nodes as streams, destroying device semantics

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...
