CVE-2022-50352

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: hns: fix possible memory leak in hnae_ae_register()<br /> <br /> Inject fault while probing module, if device_register() fails,<br /> but the refcount of kobject is not decreased to 0, the name<br /> allocated in dev_set_name() is leaked. Fix this by calling<br /> put_device(), so that name can be freed in callback function<br /> kobject_cleanup().<br /> <br /> unreferenced object 0xffff00c01aba2100 (size 128):<br /> comm "systemd-udevd", pid 1259, jiffies 4294903284 (age 294.152s)<br /> hex dump (first 32 bytes):<br /> 68 6e 61 65 30 00 00 00 18 21 ba 1a c0 00 ff ff hnae0....!......<br /> 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................<br /> backtrace:<br /> [] slab_post_alloc_hook+0xa0/0x3e0<br /> [] __kmem_cache_alloc_node+0x164/0x2b0<br /> [] __kmalloc_node_track_caller+0x6c/0x390<br /> [] kvasprintf+0x8c/0x118<br /> [] kvasprintf_const+0x60/0xc8<br /> [] kobject_set_name_vargs+0x3c/0xc0<br /> [] dev_set_name+0x7c/0xa0<br /> [] hnae_ae_register+0xcc/0x190 [hnae]<br /> [] hns_dsaf_ae_init+0x9c/0x108 [hns_dsaf]<br /> [] hns_dsaf_probe+0x548/0x748 [hns_dsaf]
