Zoo Design Studio: Memory-corruption in memory handling of lib-kcl

A race condition in kcl-lib can result in a use-after-free when accessing environments concurrently. During Vec reallocation, the previous buffer containing Box pointers is freed and replaced. A concurrent getenv operation that has already loaded a pointer to the old buffer may subsequently index...

CVE-2026-72340

A flaw was found in the Linux kernel's Microchip VCAP driver. A race condition exists in the shared Super VCAP block, where independent locking of VCAP instances can lead to concurrent access issues. A local attacker with the ability to trigger concurrent operations, such as a full rule dump in...
