Summary
In the Linux kernel, the following vulnerability has been resolved: iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init() dev_set_name() allocates memory for name, it need be freed when device_add() fails, call put_device() to give up the reference that hold in device_initialize(), so that it can be freed in kobject_cleanup() when the refcount hit to 0. Fault injection test can trigger this: unreferenced object 0xffff8e8340a7b4c0 (size 32): comm "modprobe", pid 243, jiffies 4294678145 (age 48.845s) hex dump (first 32 bytes): 69 69 6f 5f 73 79 73 66 73 5f 74 72 69 67 67 65 iio_sysfs_trigge 72 00 a7 40 83 8e ff ff 00 86 13 c4 f6 ee ff ff r..@............ backtrace: [<0000000074999de8>] __kmem_cache_alloc_node+0x1e9/0x360 [<00000000497fd30b>] __kmalloc_node_track_caller+0x44/0x1a0 [<000000003636c520>] kstrdup+0x2d/0x60 [<0000000032f84da2>] kobject_set_name_vargs+0x1e/0x90 [<0000000092efe493>] dev_set_name+0x4e/0x70
