  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvxlan: Fix memory leaks in error path\n\nThe memory allocated by vxlan_vnigroup_init() is not freed in the error\npath, leading to memory leaks [1]. Fix by calling\nvxlan_vnigroup_uninit() in the error path.\n\nThe leaks can be reproduced by annotating gro_cells_init() with\nALLOW_ERROR_INJECTION() and then running:\n\n # echo \"100\" > /sys/kernel/debug/fail_function/probability\n # echo \"1\" > /sys/kernel/debug/fail_function/times\n # echo \"gro_cells_init\" > /sys/kernel/debug/fail_function/inject\n # printf %#x -12 > /sys/kernel/debug/fail_function/gro_cells_init/retval\n # ip link add name vxlan0 type vxlan dstport 4789 external vnifilter\n RTNETLINK answers: Cannot allocate memory\n\n[1]\nunreferenced object 0xffff88810db84a00 (size 512):\n  comm \"ip\", pid 330, jiffies 4295010045 (age 66.016s)\n  hex dump (first 32 bytes):\n    f8 d5 76 0e 81 88 ff ff 01 00 00 00 00 00 00 02  ..v.............\n    03 00 04 00 48 00 00 00 00 00 00 01 04 00 01 00  ....H...........\n  backtrace:\n    [<ffffffff81a3097a>] kmalloc_trace+0x2a/0x60\n    [<ffffffff82f049fc>] vxlan_vnigroup_init+0x4c/0x160\n    [<ffffffff82ecd69e>] vxlan_init+0x1ae/0x280\n    [<ffffffff836858ca>] register_netdevice+0x57a/0x16d0\n    [<ffffffff82ef67b7>] __vxlan_dev_create+0x7c7/0xa50\n    [<ffffffff82ef6ce6>] vxlan_newlink+0xd6/0x130\n    [<ffffffff836d02ab>] __rtnl_newlink+0x112b/0x18a0\n    [<ffffffff836d0a8c>] rtnl_newlink+0x6c/0xa0\n    [<ffffffff836c0ddf>] rtnetlink_rcv_msg+0x43f/0xd40\n    [<ffffffff83908ce0>] netlink_rcv_skb+0x170/0x440\n    [<ffffffff839066af>] netlink_unicast+0x53f/0x810\n    [<ffffffff839072d8>] netlink_sendmsg+0x958/0xe70\n    [<ffffffff835c319f>] ____sys_sendmsg+0x78f/0xa90\n    [<ffffffff835cd6da>] ___sys_sendmsg+0x13a/0x1e0\n    [<ffffffff835cd94c>] __sys_sendmsg+0x11c/0x1f0\n    [<ffffffff8424da78>] do_syscall_64+0x38/0x80\nunreferenced object 0xffff88810e76d5f8 (size 192):\n  comm \"ip\", pid 330, jiffies 4295010045 (age 66.016s)\n  hex dump (first 32 bytes):\n    04 00 00 00 00 00 00 00 db e1 4f e7 00 00 00 00  ..........O.....\n    08 d6 76 0e 81 88 ff ff 08 d6 76 0e 81 88 ff ff  ..v.......v.....\n  backtrace:\n    [<ffffffff81a3162e>] __kmalloc_node+0x4e/0x90\n    [<ffffffff81a0e166>] kvmalloc_node+0xa6/0x1f0\n    [<ffffffff8276e1a3>] bucket_table_alloc.isra.0+0x83/0x460\n    [<ffffffff8276f18b>] rhashtable_init+0x43b/0x7c0\n    [<ffffffff82f04a1c>] vxlan_vnigroup_init+0x6c/0x160\n    [<ffffffff82ecd69e>] vxlan_init+0x1ae/0x280\n    [<ffffffff836858ca>] register_netdevice+0x57a/0x16d0\n    [<ffffffff82ef67b7>] __vxlan_dev_create+0x7c7/0xa50\n    [<ffffffff82ef6ce6>] vxlan_newlink+0xd6/0x130\n    [<ffffffff836d02ab>] __rtnl_newlink+0x112b/0x18a0\n    [<ffffffff836d0a8c>] rtnl_newlink+0x6c/0xa0\n    [<ffffffff836c0ddf>] rtnetlink_rcv_msg+0x43f/0xd40\n    [<ffffffff83908ce0>] netlink_rcv_skb+0x170/0x440\n    [<ffffffff839066af>] netlink_unicast+0x53f/0x810\n    [<ffffffff839072d8>] netlink_sendmsg+0x958/0xe70\n    [<ffffffff835c319f>] ____sys_sendmsg+0x78f/0xa90",
