What to do

AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel by modifying the locking mechanism to use xa_store_irq() and xa_erase_irq() to avoid deadlocks. Users should apply the official kernel updates that include this fix. Since no vendor advisory or patch links are provided, check the Linux kernel mailing lists or official repositories for the patch and update accordingly.

Description

CVE-2024-38591 is a medium-severity vulnerability in the Linux kernel's RDMA hns driver related to a deadlock condition on Shared Receive Queue (SRQ) asynchronous events. The issue arises because the xa_lock for the SRQ table may be required in the Asynchronous Event Queue (AEQ), potentially causing a deadlock. The fix involves using xa_store_irq() and xa_erase_irq() functions to avoid this deadlock scenario.
