Summary
CVE-2024-56651 is a vulnerability affecting the Linux kernel's CAN (Controller Area Network) subsystem. The issue arises from a commit that removed the reporting of rxerr and txerr during regular operation, leading to potential use-after-free vulnerabilities. Specifically, error count information added to the CAN frame after netif_rx() call may be accessed after the skb (Socket Buffer) is freed or reused. This vulnerability has been resolved by postponing the netif_rx() call in case of txerr and rxerr reporting.
