Vulnerability details

The vulnerability allows a local user to potentially cause a denial of service.

The vulnerability exists due to improper resource lifetime management in the Linux kernel samsung-dsim driver's TE GPIO handling when registering and unregistering the TE interrupt during DSI host attachment and detachment. A local user can potentially trigger conflicting manual and device-managed releases of the GPIO descriptor to disrupt driver operation and cause a denial of service.
