Description

In the Linux kernel, the following vulnerability has been resolved: net: ti: icss-iep: Fix possible NULL pointer dereference for perout request The ICSS IEP driver tracks perout and pps enable state with flags. Currently when disabling pps and perout signals during icss_iep_exit(), results in NULL pointer dereference for perout. To fix the null pointer dereference issue, the icss_iep_perout_enable_hw function can be modified to directly clear the IEP CMP registers when disabling PPS or PEROUT, without referencing the ptp_perout_request structure, as its contents are irrelevant in this case.
