In the Linux kernel, the following vulnerability has been resolved:

media: chips-media: wave5: Resume device before setting EOS flag

Setting the EOS flag talks to the firmware via send_firmware_command(), which accesses VPU registers. Both the STREAMOFF path (wave5_vpu_dec_job_abort()) and the V4L2_DEC_CMD_STOP path (wave5_vpu_dec_stop()) can run while the device is runtime suspended, so those register accesses hit powered-down hardware and the SoC raises an asynchronous SError, panicking the kernel:

SError Interrupt on CPU3, code 0x00000000bf000000 -- SError send_firmware_command+0x2c/0x160 [wave5] wave5_vpu_dec_set_bitstream_flag+0x6c/0x80 [wave5] wave5_vpu_dec_update_bitstream_buffer+0x80/0xec [wave5] wave5_vpu_dec_job_abort+0x44/0xa0 [wave5] v4l2_m2m_cancel_job+0x110/0x19c [v4l2_mem2mem] v4l2_m2m_streamoff+0x24/0x140 [v4l2_mem2mem]

Resume the device with pm_runtime_resume_and_get() around the EOS firmware command and release it with pm_runtime_put_autosuspend(), matching the runtime PM handling already done in wave5_vpu_dec_device_run().
