The Chainguard security team deemed this advisory irrelevant for Chainguard:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-qemu-6.18 package and not the linux-qemu-6.18 package as distributed by Chainguard.
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Add missing NULL check for alloc_workqueue()
alloc_workqueue() can return NULL on memory allocation failure. Without proper error checking, this may lead to a NULL pointer dereference when queue_work() is later called with the NULL workqueue pointer in epf_ntb_epc_init().
Add a NULL check immediately after alloc_workqueue() and return -ENOMEM on failure to prevent the driver from loading with an invalid workqueue pointer.
