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
