CVE-2026-46247

In the Linux kernel, the following vulnerability has been resolved: clk: qcom: gfx3d: add parent to parent request map After commit d228ece36345 ("clk: divider: remove round_rate() in favor of determine_rate()") determining GFX3D clock rate crashes, because the passed parent map doesn't provide the expected best_parent_hw clock (with the roundd_rate path before the offending commit the best_parent_hw was ignored). Set the field in parent_req in addition to setting it in the req, fixing the crash. clk_hw_round_rate (drivers/clk/clk.c:1764) (P) clk_divider_bestdiv (drivers/clk/clk-divider.c:336) divider_determine_rate (drivers/clk/clk-divider.c:358) clk_alpha_pll_postdiv_determine_rate (drivers/clk/qcom/clk-alpha-pll.c:1275) clk_core_determine_round_nolock (drivers/clk/clk.c:1606) clk_core_round_rate_nolock (drivers/clk/clk.c:1701) __clk_determine_rate (drivers/clk/clk.c:1741) clk_gfx3d_determine_rate (drivers/clk/qcom/clk-rcg2.c:1268) clk_core_determine_round_nolock (drivers/clk/clk.c:1606) clk_core_round_rate_nolock (drivers/clk/clk.c:1701) clk_core_round_rate_nolock (drivers/clk/clk.c:1710) clk_round_rate (drivers/clk/clk.c:1804) dev_pm_opp_set_rate (drivers/opp/core.c:1440 (discriminator 1)) msm_devfreq_target (drivers/gpu/drm/msm/msm_gpu_devfreq.c:51) devfreq_set_target (drivers/devfreq/devfreq.c:360) devfreq_update_target (drivers/devfreq/devfreq.c:426) devfreq_monitor (drivers/devfreq/devfreq.c:458) process_one_work (arch/arm64/include/asm/jump_label.h:36 include/trace/events/workqueue.h:110 kernel/workqueue.c:3284) worker_thread (kernel/workqueue.c:3356 (discriminator 2) kernel/workqueue.c:3443 (discriminator 2)) kthread (kernel/kthread.c:467) ret_from_fork (arch/arm64/kernel/entry.S:861)
