CVE-2026-80651

A flaw was found in the Linux kernel's crypto: ccp/sev-dev-tsm module. The dsmcreate function fails to properly validate the pdev-bus pointer, leading to a null pointer dereference. A local attacker could exploit this vulnerability to trigger a kernel crash, resulting in a Denial of Service DoS...
