media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe

Type: advisorySource: OSV1 source record

In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe Both mxc_isi_crossbar_init() and mxc_isi_pipe_init() call v4l2_subdev_init_finalize() which allocates the subdev active state, but neither mxc_isi_crossbar_cleanup() nor mxc_isi_pipe_cleanup() calls v4l2_subdev_cleanup() to free it. This causes a memory leak on every rmmod, reported by kmemleak: unreferenced object 0xffff0000d06fc800 (size 192): comm "(udev-worker)", pid 254, jiffies 4294913455 backtrace (crc 36eeae58): kmemleak_alloc+0x34/0x40 __kvmalloc_node_noprof+0x5f8/0x7d8 __v4l2_subdev_state_alloc+0x1fc/0x30c __v4l2_subdev_init_finalize+0x178/0x368 Add the missing v4l2_subdev_cleanup() calls before media_entity_cleanup() in both crossbar and pipe cleanup paths.
