Description
In the Linux kernel, the following vulnerability has been resolved:
OPP: Fix cleanup ordering
Commit 173e02d67494 ("OPP: Initialize scope-based pointers inline") added initialization for all pointers. In some cases, the ordering was changed so that *opp_table was initialized after *opp. This also changes the order of the registered cleanup functions.
When the cleanup happens, this can cause use-after-free errors when the last reference is released and the release function _opp_kref_release tries to access the already freed opp->opp_table.
Initialize *opp_table before *opp again to fix this and ensure the correct cleanup order.
