In the Linux kernel, the following vulnerability has been resolved: drivers: staging: rtl8192bs: Fix deadlock in rtw_joinbss_event_prehandle() There is a deadlock in rtw_joinbss_event_prehandle(), which is shown below: (Thread 1) | (Thread 2) | _set_timer() rtw_joinbss_event_prehandle()| mod_timer() spin_lock_bh() //(1) | (wait a time) ... | _rtw_join_timeout_handler() del_timer_sync() | spin_lock_bh() //(2) (wait timer to stop) | ... We hold pmlmepriv->lock in position (1) of thread 1 and use del_timer_sync() to wait timer to stop, but timer handler also need pmlmepriv->lock in position (2) of thread 2. As a result, rtw_joinbss_event_prehandle() will block forever. This patch extracts del_timer_sync() from the protection of spin_lock_bh(), which could let timer handler to obtain the needed lock. What`s more, we change spin_lock_bh() to spin_lock_irq() in _rtw_join_timeout_handler() in order to prevent deadlock.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006590 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    drivers: staging: rtl8192bs: Fix deadlock in rtw_joinbss_event_prehandle()

    There is a deadlock in rtw_joinbss_event_prehandle(), which is shown     below:

       (Thread 1)                |      (Thread 2)                                  | _set_timer()     rtw_joinbss_event_prehandle()|  mod_timer()      spin_lock_bh() //(1)        |  (wait a time)      ...                         | _rtw_join_timeout_handler()      del_timer_sync()            |  spin_lock_bh() //(2)      (wait timer to stop)        |  ...

    We hold pmlmepriv->lock in position (1) of thread 1 and     use del_timer_sync() to wait timer to stop, but timer handler     also need pmlmepriv->lock in position (2) of thread 2.
    As a result, rtw_joinbss_event_prehandle() will block forever.

    This patch extracts del_timer_sync() from the protection of     spin_lock_bh(), which could let timer handler to obtain     the needed lock. What`s more, we change spin_lock_bh() to     spin_lock_irq() in _rtw_join_timeout_handler() in order to     prevent deadlock.
