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. The Linux kernel CVE team has assigned CVE-2026-93069 to this issue. Affected and fixed versions =========================== Issue introduced in 6.19 with commit 173e02d674946ff3ef8da7f44a9d5b820b9af21c and fixed in 7.2.6 with commit f0c4b7ca24d2e2618a70826881d69b237e36bcc0 Issue introduced in 6.19 with commit 173e02d674946ff3ef8da7f44a9d5b820b9af21c and fixed in 7.3-rc1 with commit ce46fede7792cedd247e34b48bc8a02eb90c7848 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-93069 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/opp/core.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/f0c4b7ca24d2e2618a70826881d69b237e36bcc0 https://git.kernel.org/stable/c/ce46fede7792cedd247e34b48bc8a02eb90c7848
