UBUNTU-CVE-2026-93069: Use After Free

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 opptable 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 oppkrefrelease tries to access the already freed opp->opptable. Initialize opptable before opp again to fix this and ensure the correct cleanup order.
