CVE-2026-10653 Non-atomic `net_buf` reference counts cause double-free / free-list corruption under concurrent unref

The Zephyr netbuf library lib/netbuf/buf.c manipulated both of its reference counts -- the per-header buf-ref and the per-data-block refcount at the start of each variable/heap data allocation -- with plain non-atomic C operators buf-ref++, if --buf-ref 0, if --refcount. The API is documented as...

[SECURITY] Fedora 44 Update: valkey-9.0.4-1.fc44

Valkey is an advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing to a list; computing s...
