CVE-2023-52593 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap() Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()' should check the return value before examining skb data. So convert the latter to return an appropriate error code and propagate it to return from 'wfx_start_ap()' as well. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
