CVE-2022-50650

The CVE-2022-50650 entry concerns the Linux kernel BPF verifier and synchronous callbacks. The issue arises because the verifier treats callbacks as if they execute only once, which mismanages reference state for for_each style helpers that invoke callbacks multiple times. This can lead to refere...
