Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the
pm8916 lbc supply driver. The problem occurs because the interrupt request (IRQ) is requested before the extcon handle is allocated using devm variants. Since devm deallocates resources in reverse order of allocation, the extcon handle is freed before the IRQ handler is unregistered during removal. This creates a race condition where an interrupt can trigger after the extcon handle is freed but before the IRQ handler is removed, leading to a call to the extcon set state sync() function with a freed handle, which may cause system crashes or memory corruption.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
