CVE-2025-21775

CVE-2025-21775 affects the Linux kernel CAN ctucanfd component. When skb allocation fails, the can_frame pointer can be NULL, and one NULL check was missed in ctucan_err_interrupt(); a fix adding the NULL check was implemented in the kernel (see references to the can: ctucanfd: handle skb allocat...

CVE-2025-21775 can: ctucanfd: handle skb allocation failure

In the Linux kernel, the following vulnerability has been resolved: can: ctucanfd: handle skb allocation failure If skb allocation fails, the pointer to struct canframe is NULL. This is actually handled everywhere inside ctucanerrinterrupt except for the only place. Add the missed NULL check. Fou...
