CVE-2025-71140 (CNNVD-202601-2415)
中文标题:
Linux kernel 安全漏洞
英文标题:
media: mediatek: vcodec: Use spinlock for context list protection lock
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于在硬IRQ上下文中使用互斥锁保护上下文列表，可能导致调度器警告。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Use spinlock for context list protection lock Previously a mutex was added to protect the encoder and decoder context lists from unexpected changes originating from the SCP IP block, causing the context pointer to go invalid, resulting in a NULL pointer dereference in the IPI handler. Turns out on the MT8173, the VPU IPI handler is called from hard IRQ context. This causes a big warning from the scheduler. This was first reported downstream on the ChromeOS kernels, but is also reproducible on mainline using Fluster with the FFmpeg v4l2m2m decoders. Even though the actual capture format is not supported, the affected code paths are triggered. Since this lock just protects the context list and operations on it are very fast, it should be OK to switch to a spinlock.
