 - In the Linux kernel, the following vulnerability has been resolved: Input: cros_ec_keyb - fix an invalid
 memory access If cros_ec_keyb_register_matrix() isn't called (due to `buttons_switches_only`) in
 cros_ec_keyb_probe(), `ckdev->idev` remains NULL. An invalid memory access is observed in
 cros_ec_keyb_process() when receiving an EC_MKBP_EVENT_KEY_MATRIX event in cros_ec_keyb_work() in such
 case. Unable to handle kernel read from unreadable memory at virtual address 0000000000000028 ... x3 :
 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000000 Call trace: input_event
 cros_ec_keyb_work blocking_notifier_call_chain ec_irq_thread It's still unknown about why the kernel
 receives such malformed event, in any cases, the kernel shouldn't access `ckdev->idev` and friends if the
 driver doesn't intend to initialize them. (CVE-2025-40263)
