kernel: Linux kernel: Use-after-free vulnerability in page_pool_recycle_in_ring can lead to arbitrary code execution

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free UAF, occurs in the pagepoolrecycleinring function. A local attacker could exploit this by manipulating the system's memory management, causing a freed memory region to be improperly accessed. This can lead to syst...
