| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: fix possible use-after-free in smsc75xx_bind\n\nThe commit 46a8b29c6306 (\"net: usb: fix memory leak in smsc75xx_bind\")\nfails to clean up the work scheduled in smsc75xx_reset->\nsmsc75xx_set_multicast, which leads to use-after-free if the work is\nscheduled to start after the deallocation. In addition, this patch\nalso removes a dangling pointer - dev->data[0].\n\nThis patch calls cancel_work_sync to cancel the scheduled work and set\nthe dangling pointer to NULL." |
