Vulnerabilidad en Linux (CVE-2026-46247)

En el kernel de Linux, la siguiente vulnerabilidad se ha resuelto:<br /> <br /> clk: qcom: gfx3d: añadir padre al mapa de solicitud de padre<br /> <br /> Después del commit d228ece36345 (&amp;#39;clk: divider: eliminar round_rate() en favor<br /> de determine_rate()&amp;#39;) la determinación de la frecuencia del reloj GFX3D falla, porque el<br /> mapa de padre pasado no proporciona el reloj best_parent_hw esperado<br /> (con la ruta roundd_rate antes del commit problemático, el<br /> best_parent_hw era ignorado).<br /> <br /> Establecer el campo en parent_req además de establecerlo en req,<br /> solucionando la falla.<br /> <br /> clk_hw_round_rate (drivers/clk/clk.c:1764) (P)<br /> clk_divider_bestdiv (drivers/clk/clk-divider.c:336)<br /> divider_determine_rate (drivers/clk/clk-divider.c:358)<br /> clk_alpha_pll_postdiv_determine_rate (drivers/clk/qcom/clk-alpha-pll.c:1275)<br /> clk_core_determine_round_nolock (drivers/clk/clk.c:1606)<br /> clk_core_round_rate_nolock (drivers/clk/clk.c:1701)<br /> __clk_determine_rate (drivers/clk/clk.c:1741)<br /> clk_gfx3d_determine_rate (drivers/clk/qcom/clk-rcg2.c:1268)<br /> clk_core_determine_round_nolock (drivers/clk/clk.c:1606)<br /> clk_core_round_rate_nolock (drivers/clk/clk.c:1701)<br /> clk_core_round_rate_nolock (drivers/clk/clk.c:1710)<br /> clk_round_rate (drivers/clk/clk.c:1804)<br /> dev_pm_opp_set_rate (drivers/opp/core.c:1440 (discriminator 1))<br /> msm_devfreq_target (drivers/gpu/drm/msm/msm_gpu_devfreq.c:51)<br /> devfreq_set_target (drivers/devfreq/devfreq.c:360)<br /> devfreq_update_target (drivers/devfreq/devfreq.c:426)<br /> devfreq_monitor (drivers/devfreq/devfreq.c:458)<br /> process_one_work (arch/arm64/include/asm/jump_label.h:36 include/trace/events/workqueue.h:110 kernel/workqueue.c:3284)<br /> worker_thread (kernel/workqueue.c:3356 (discriminator 2) kernel/workqueue.c:3443 (discriminator 2))<br /> kthread (kernel/kthread.c:467)<br /> ret_from_fork (arch/arm64/kernel/entry.S:861)
