Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drivers: staging: rtl8192u: Fix deadlock in ieee80211_beacons_stop() There is a deadlock in     ieee80211_beacons_stop(), which is shown below: (Thread 1) | (Thread 2) | ieee80211_send_beacon()     ieee80211_beacons_stop() | mod_timer() spin_lock_irqsave() //(1) | (wait a time) ... |     ieee80211_send_beacon_cb() del_timer_sync() | spin_lock_irqsave() //(2) (wait timer to stop) | ... We hold     ieee->beacon_lock in position (1) of thread 1 and use del_timer_sync() to wait timer to stop, but timer     handler also need ieee->beacon_lock in position (2) of thread 2. As a result, ieee80211_beacons_stop()     will block forever. This patch extracts del_timer_sync() from the protection of spin_lock_irqsave(), which     could let timer handler to obtain the needed lock. (CVE-2022-49305)

Note that Nessus relies on the presence of the package as reported by the vendor.
