  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct()\n\nPassing MSG_PEEK flag to skb_recv_datagram() increments skb refcount\n(skb->users) and iucv_sock_recvmsg() does not decrement skb refcount\nat exit.\nThis results in skb memory leak in skb_queue_purge() and WARN_ON in\niucv_sock_destruct() during socket close. To fix this decrease\nskb refcount by one if MSG_PEEK is set in order to prevent memory\nleak and WARN_ON.\n\nWARNING: CPU: 2 PID: 6292 at net/iucv/af_iucv.c:286 iucv_sock_destruct+0x144/0x1a0 [af_iucv]\nCPU: 2 PID: 6292 Comm: afiucv_test_msg Kdump: loaded Tainted: G        W          6.10.0-rc7 #1\nHardware name: IBM 3931 A01 704 (z/VM 7.3.0)\nCall Trace:\n        [<001587c682c4aa98>] iucv_sock_destruct+0x148/0x1a0 [af_iucv]\n        [<001587c682c4a9d0>] iucv_sock_destruct+0x80/0x1a0 [af_iucv]\n        [<001587c704117a32>] __sk_destruct+0x52/0x550\n        [<001587c704104a54>] __sock_release+0xa4/0x230\n        [<001587c704104c0c>] sock_close+0x2c/0x40\n        [<001587c702c5f5a8>] __fput+0x2e8/0x970\n        [<001587c7024148c4>] task_work_run+0x1c4/0x2c0\n        [<001587c7023b0716>] do_exit+0x996/0x1050\n        [<001587c7023b13aa>] do_group_exit+0x13a/0x360\n        [<001587c7023b1626>] __s390x_sys_exit_group+0x56/0x60\n        [<001587c7022bccca>] do_syscall+0x27a/0x380\n        [<001587c7049a6a0c>] __do_syscall+0x9c/0x160\n        [<001587c7049ce8a8>] system_call+0x70/0x98\n        Last Breaking-Event-Address:\n        [<001587c682c4a9d4>] iucv_sock_destruct+0x84/0x1a0 [af_iucv]",
