  "details": "In the Linux kernel, the following vulnerability has been resolved:  md/raid1: create serial pool adding rdev to array with serialize_policy=1  The following bug has been observed with kernel 7.1.3 after adding a new rdev to an existing RAID1 array with serialize_policy enabled:    Oops: 0002 [#1]   CPU: 0 UID: 0 PID: 19639 Comm: ext4lazyinit Not tainted 7.1.3-1-default   RIP: _raw_spin_lock_irqsave+0x27/0x50   CR2: 0000000000004960   Call Trace:    wait_for_serialization+0xb9/0x260 [raid1]    raid1_make_request+0x762/0xaff [raid1]    md_handle_request+0x1c9/0x2e0 [md_mod]  The raid1.c code calls wait_for_serialization() if the MD_SERIALIZE_POLICY is set, and wait_for_serialization assumes that rdev-\u003eserial is initialized. Normally this will be the case for arrays that have the serialize_policy sysfs attribute set to 1.  But when a new rdev is added to an existing array in bind_rdev_to_array(), the condition at mddev_create_serial_pool() causes creation of rdev-\u003eserial to be skipped. Fix it.",
