CVE-2026-43981

Algernon is a small self-contained pure-Go web server. Prior to 1.17.6, in engine/luahandler.go, the sync.RWMutex protecting LoadCommonFunctions is released before L.Push and L.PCall execute. Since gopher-lua's LState is explicitly not goroutine-safe, concurrent requests race on the shared state...

CVE-2026-43499

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

CVE-2026-43499

The CVE-2026-43499 issue concerns the Linux kernel rtmutex path where remove_waiter() operated on current during dequeue in rt_mutex_start_proxy_lock() via futex_requeue(). This caused: (1) rbtree dequeue without waiter::task::pi_lock, (2) waiter task pi_blocked_on not cleared (dangling pointer, ...
