CVE-2025-21798

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A potential null dereference issue has been identified in the firewire kunit test of the Linux kernel. The kunit kzalloc() function may return a NULL pointer, and without a proper NULL check, dereferencing it could lead to a null dereference. This issue is resolved by adding a NULL check for test state.

Recommendations For the affected Linux kernel version, add a NULL check for test state to prevent potential null dereference.
