  "details": "In the Linux kernel, the following vulnerability has been resolved:  cxl/mbox: Break poison list loop on an empty payload  A device that returns count == 0 with CXL_POISON_FLAG_MORE set on every iteration never advances nr_records, so the max_errors guard never trips and the do/while loops forever while holding poison.mutex. That hangs the sysfs-triggered scan thread and blocks all subsequent poison operations on the device. The existing \"Protect against an uncleared _FLAG_MORE\" guard was intended to bound a misbehaving device but does not cover the count == 0 case.  Stop the loop on an empty payload so a malfunctioning or malicious device cannot wedge the poison scan.",
