CVE-2026-53278

CVE-2026-53278 affects the Linux kernel arm_mpam component. The vulnerability arises when __destroy_component_cfg() is invoked from mpam_disable() before the configuration array has been allocated, causing a NULL pointer dereference. The function frees the configuration array and mbwu_state; sinc...
