medium Tenable Self-Hosted Container Security Plugin ID 457553

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Avoid creating sub-
 groups asynchronously The asynchronous creation of sub-groups by a delayed work could lead to a NULL
 pointer dereference when the driver directory is removed before the work completes. The crash can be
 easily reproduced with the following commands: # cd /sys/kernel/config/pci_ep/functions/pci_epf_test # for
 i in {1..20}; do mkdir test && rmdir test; done BUG: kernel NULL pointer dereference, address:
 0000000000000088 ... Call Trace: configfs_register_group+0x3d/0x190 pci_epf_cfs_work+0x41/0x110
 process_one_work+0x18f/0x350 worker_thread+0x25a/0x3a0 Fix this issue by using
 configfs_add_default_group() API which does not have the deadlock problem as configfs_register_group() and
 does not require the delayed work handler. [mani: slightly reworded the description and added stable list]
