CVE-2024-58064

KUnit test crash via unchecked allocation failure

Published Mar 6, 2025 · Updated May 11, 2026

NULL pointer dereference in Linux kernel cfg80211 test code allows local users to crash a KUnit test after a memory-allocation failure. test_cfg80211_parse_colocated_ap() assigns the result of kunit_kzalloc() to ies, then writes through ies and copies data into it without first checking for NULL. Reachability requires a kernel built with the cfg80211 KUnit test and execution of that test; ordinary Wi-Fi traffic does not invoke the affected test function.
