Описание
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Avoid potential ndlp use-after-free in dev_loss_tmo_callbk
Smatch detected a potential use-after-free of an ndlp oject in
dev_loss_tmo_callbk during driver unload or fatal error handling.
Fix by reordering code to avoid potential use-after-free if initial
nodelist reference has been previously removed.
A flaw was found in the Linux kernel's scsi: lpfc component. This vulnerability involves a use-after-free error in the dev_loss_tmo_callbk function. During driver unload or fatal error handling, a previously freed object could be accessed. This could allow a local attacker to cause a system crash, leading to a denial of service.
