AI-suggested

A fix is available that corrects the initialization order of pointers in the OPP subsystem. Users should apply the updated Linux kernel versions that include this fix. No additional mitigation actions are indicated.

Description

A use-after-free vulnerability in the Linux kernel's OPP (Operating Performance Points) subsystem was fixed by correcting the cleanup ordering of pointers. The issue occurred because the opp_table pointer was initialized after opp, leading to a scenario where the release function accessed already freed memory. This flaw has been resolved by initializing opp_table before opp to ensure proper cleanup order.
