Vulnerability from github
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:
