RUSTSEC-2026-0142 Double-free in `vmem` storage reachable from safe Rust (predecessor of `oneringbuf`)

mutringbuf is the archived predecessor of oneringbuf — the crate was renamed and the GitHub repository was archived on 2025-11-20. All released versions up to 1.0.0 carry the same vmem-feature double-free bug that affects oneringbuf, with the same code paths and the same reproduction shape. When...

Double-free in `vmem` storage reachable from safe Rust

When the vmem feature is enabled, VmemStorage::newBox and every public constructor that funnels through it — ConcurrentHeapRB::defaultcap, ConcurrentHeapRB::fromVec, From, etc. bit-copies the input buffer into a freshly mmap'd region with ptr::copynonoverlapping, then lets the source Box drop...

The vulnerability of the vmem_map_init() function in the arch/s390/mm/vmem.c module of the S390 platform support for Linux’s operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the vmemmapinit function in the arch/s390/mm/vmem.c module of the S390 platform support for the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
