CVE-2023-53281

Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)

Description The Linux kernel contains an issue within the rtl8723bs driver related to locking in the rtw join timeout handler() function. A modification to use spin [un]lock irq() instead of spin [un]lock bh() within this function caused an oops in kernel/softirq.c due to unnecessary disabling of Interrupt Requests (IRQs). The rtw join timeout handler() function calls rtw do join(), which acquires pmlmepriv->scanned queue.lock using spin [un]lock bh(). Re-enabling softirqs via spin unlock bh() triggered the error.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
