In the Linux kernel, the following vulnerability has been resolved: clk: mediatek: Drop __initconst from gates Since commit 8ceff24a754a ("clk: mediatek: clk-gate: Refactor mtk_clk_register_gate to use mtk_gate struct") the mtk_gate structs are no longer just used for initialization/registration, but also at runtime. So drop __initconst annotations.

In the Linux kernel, the following vulnerability has been resolved: soc: mediatek: svs: Fix memory leak in svs_enable_debug_write() In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails. Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks. [Angelo: Added missing cleanup.h inclusion]

Use-after-free in Linux kernel MediaTek video encoder allows local authenticated users to corrupt memory and potentially execute arbitrary code. The flaw affects the vcodec driver's encoder release path where ctx memory is freed before canceling scheduled workqueue tasks, enabling race conditions between cleanup and worker threads that may dereference freed memory. KASAN-confirmed exploitation requires local access with low privileges (CVSS AV:L/PR:L). Patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% (5th percentile) indicates very low probability of automated exploitation, with no public exploit identified at time of analysis.

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: dsi: Store driver data before invoking mipi_dsi_host_register The call to mipi_dsi_host_register triggers a callback to mtk_dsi_bind, which uses dev_get_drvdata to retrieve the mtk_dsi struct, so this structure needs to be stored inside the driver data before invoking it. As drvdata is currently uninitialized it leads to a crash when registering the DSI DRM encoder right after acquiring the mode_config.idr_mutex, blocking all subsequent DRM operations.
