Threats tagged 'ghsa-247j-3qhv-rpc8'

A critical vulnerability in the Linux kernel's nvmet-fc subsystem involves scheduling association deletion twice during forced port shutdown via the configfs interface. The flaw arises because the system schedules deletion work items without properly preventing duplicate scheduling, potentially leading to double-free scenarios. This occurs as the association list uses RCU synchronization, preventing direct locking and removal, requiring a flag to track deletion status. The vulnerability has been resolved in the Linux kernel.
