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...

Algernon: Race condition issues

Algernon is a web server developed by Alexander F. Rødseth. Versions of Algernon prior to 1.17.6 contained a race condition vulnerability. This vulnerability stemmed from the sync.RWMutex used in engine/luahandler.go to protect LoadCommonFunctions, which was released before L.Push and L.PCall...

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 rtmutex: Use waiter::task instead of current in remove_waiter()

In the Linux kernel, the following vulnerability has been resolved: rtmutex: Use waiter::task instead of current in removewaiter removewaiter is used by the slowlock paths, but it is also used for proxy-lock rollback in rtmutexstartproxylock when invoked from futexrequeue. In the latter case...

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, ...

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: Fixed atomic context locking issue The ncmsetalt function was holding a mutex to prevent race conditions with configfs. This function invokes the mightsleep function within an atomic context. The struct pointer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: HID: corsair-void: Update power supply values using a unified work handler. The function corsairvoidprocessreceiver can be called from an interrupt context. However, locking the batterymutex in this function caused a kernel panic...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: perf/core: Fixed a reference count bug and a potential UAF in perfmmap. Syzkaller reported a refcountt issue where the increment of the reference count was set to 0; there was also a warning about a use-after-free when using...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mac80211: Fixed a deadlock issue in AP/VLAN handling. Syzbot reports that when APVLAN interfaces are active, closing the AP interface they belong to can lead to a deadlock. This isn’t surprising—since we use devclose to handle...
