CVE-2025-21775
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
can: ctucanfd: handle skb allocation failure
If skb allocation fails, the pointer to struct can_frame is NULL. This is actually handled everywhere inside ctucan_err_interrupt() except for the only place.
Add the missed NULL check.
Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
