CVE-2022-49544 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ipw2x00: Fix potential NULL dereference in libipw_xmit() crypt and crypt->ops could be null, so we need to checking null before dereference. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
