    "summary": "In the Linux kernel, the following vulnerability has been resolved: vxlan: Fix memory leaks in error path The memory allocated by vxlan_vnigroup_init() is not freed in the error path, leading to memory leaks [1]. Fix by calling vxlan_vnigroup_uninit() in the error path. The leaks can be reproduced by annotating gro_cells_init() with ALLOW_ERROR_INJECTION() and then running: # echo \"100\" > /sys/kernel/debug/fail_function/probability # echo \"1\" > /sys/kernel/debug/fail_function/times # echo \"gro_cells_init\" > /sys/kernel/debug/fail_function/inject # printf %#x -12 > /sys/kernel/debug/fail_function/gro_cells_init/retval # ip link add name vxlan0 type vxlan dstport 4789 external vnifilter RTNETLINK answers: Cannot allocate memory [1] unreferenced object 0xffff88810db84a00 (size 512): comm \"ip\", pid 330, jiffies 4295010045 (age 66.016s) hex dump (first 32 bytes): f8 d5 76 0e 81 88 ff ff 01 00 00 00 00 00 00 02 ..v............. 03 00 04 00 48 00 00 00 00 00 00 01 04 00 01 00 ....H........... backtrace: [] kmalloc_trace+0x2a/0x60 [] vxlan_vnigroup_init+0x4c/0x160 [] vxlan_init+0x1ae/0x280 [] register_netdevice+0x57a/0x16d0 [] __vxlan_dev_create+0x7c7/0xa50 [] vxlan_newlink+0xd6/0x130 [] __rtnl_newlink+0x112b/0x18a0 [] rtnl_newlink+0x6c/0xa0 [] rtnetlink_rcv_msg+0x43f/0xd40 [] netlink_rcv_skb+0x170/0x440 [] netlink_unicast+0x53f/0x810 [] netlink_sendmsg+0x958/0xe70 [] ____sys_sendmsg+0x78f/0xa90 [] ___sys_sendmsg+0x13a/0x1e0 [] __sys_sendmsg+0x11c/0x1f0 [] do_syscall_64+0x38/0x80 unr",
