5.5 · MEDIUMOverview
CVE-2022-49156 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 26, 2025 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: qla2xxx: Fix scheduling while atomic
The driver makes a call into midlayer (fc_remote_port_delete) which can put
the thread to sleep. The thread that originates the call is in interrupt
context. The combination of the two trigger a crash. Schedule the call in
non-interrupt context where it is more safe.
