CVE-2025-21798

CVE-2025-21798 concerns the Linux kernel FireWire kunit test. The vulnerability arises when kunit_kzalloc() returns NULL and test_state is dereferenced without a NULL check, potentially causing a NULL pointer dereference. A fix adds a NULL check for test_state to prevent dereferencing a NULL poin...

The vulnerability of the kunit_try_catch_run() function in the KUnit framework (lib/kunit/try-catch.c) in the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the kunittrycatchrun function in the KUnit framework lib/kunit/try-catch.c in the Linux kernel is related to the reallocation of memory after its deallocation due to concurrent access to resources race condition. Exploiting this vulnerability could allow an attacker to...
