EUVD-2026-18678

In the Linux kernel, the following vulnerability has been resolved: net: shaper: protect late read accesses to the hierarchy We look up a netdev during prep of Netlink ops pre- callbacks and take a ref to it. Then later in the body of the callback we take its lock or RCU which are the actual...

CVE-2026-23437

A flaw was found in the Linux kernel's net: shaper module. This vulnerability arises from a missing liveness check during Netlink operations when a network device netdev is referenced and subsequently accessed. If the netdev is unregistered before the access, it can lead to a use-after-free...

CVE-2026-23437

CVE-2026-23437 (Linux kernel) concerns the net: shaper module. A missing liveness check occurs when a netdev is looked up during prep of Netlink operations, a reference is taken, and later the code uses the netdev’s lock or RCU protections. The conversion from a ref to a locked netdev may proceed...

CVE-2026-23436

The CVE-2026-23436 issue affects the Linux kernel's net: shaper component. A race could occur when a netdev is unregistered between taking a reference during Netlink prep and locking/RCU in the callback, potentially leaking the hierarchy after a flush. The fix applies the instance lock in pre- st...
