Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 5.15.185/6.1.141/6.6.94/6.12.34/6.15.3. This vulnerability affects the function rproc_handle_resources of the component remoteproc. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. CVE summarizes:

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: [<00000000f949fe18>] slab_post_alloc_hook+0x98/0x37c [<00000000adbfb3e7>] __kmem_cache_alloc_node+0x138/0x2e0 [<00000000521c0345>] kmalloc_trace+0x40/0x158 [<000000004e330a49>] rproc_mem_entry_init+0x60/0xf8 [<000000002815755e>] imx_rproc_prepare+0xe0/0x180 [<0000000003f61b4e>] rproc_boot+0x2ec/0x528 [<00000000e7e994ac>] rproc_add+0x124/0x17c [<0000000048594076>] imx_rproc_probe+0x4ec/0x5d4 [<00000000efc298a1>] platform_probe+0x68/0xd8 [<00000000110be6fe>] really_probe+0x110/0x27c [<00000000e245c0ae>] __driver_probe_device+0x78/0x12c [<00000000f61f6f5e>] driver_probe_device+0x3c/0x118 [<00000000a7874938>] __device_attach_driver+0xb8/0xf8 [<0000000065319e69>] bus_for_each_drv+0x84/0xe4 [<00000000db3eb243>] __device_attach+0xfc/0x18c [<0000000072e4e1a4>] device_initial_probe+0x14/0x20
