CVE-2025-38419

In the Linux kernel, the following vulnerability has been resolved: remoteproc: core: Cleanup acquired resources when rproc_handle_resources() fails in rproc_attach() When rproc->state = RPROC_DETACHED and rproc_attach() is used to attach to the remote processor, if rproc_handle_resources() returns a failure, the resources allocated by imx_rproc_prepare() should be released, otherwise the following memory leak will occur. Since almost the same thing is done in imx_rproc_prepare() and rproc_resource_cleanup(), Function rproc_resource_cleanup() is able to deal with empty lists so it is better to fix the "goto" statements in rproc_attach(). replace the "unprepare_device" goto statement with "clean_up_resources" and get rid of the "unprepare_device" label. unreferenced object 0xffff0000861c5d00 (size 128): comm "kworker/u12:3", pid 59, jiffies 4294893509 (age 149.220s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 02 88 00 00 00 00 00 00 10 00 00 00 00 00 ............ backtrace: [ ] slab_post_alloc_hook+0x98/0x37c [ ] __kmem_cache_alloc_node+0x138/0x2e0 [ ] kmalloc_trace+0x40/0x158 [ ] rproc_mem_entry_init+0x60/0xf8 [ ] imx_rproc_prepare+0xe0/0x180 [ ] rproc_boot+0x2ec/0x528 [ ] rproc_add+0x124/0x17c [ ] imx_rproc_probe+0x4ec/0x5d4 [ ] platform_probe+0x68/0xd8 [ ] really_probe+0x110/0x27c [ ] __driver_probe_device+0x78/0x12c [ ] driver_probe_device+0x3c/0x118 [ ] __device_attach_driver+0xb8/0xf8 [ ] bus_for_each_drv+0x84/0xe4 [ ] __device_attach+0xfc/0x18c [ ] device_initial_probe+0x14/0x20
