CVE-2022-48758 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 20, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put()
The bnx2fc_destroy() functions are removing the interface before calling
destroy_work. This results multiple WARNings from sysfs_remove_group() as
the controller rport device attributes are removed too early.
Replace the fcoe_port's destroy_work queue. It's not needed.
The problem is easily reproducible with the following steps.
Example:
$ dmesg -w &
$ systemctl enable --now fcoe
$ fipvlan -s -c ens2f1
$ fcoeadm -d ens2f1.802
