In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn’t called. This issue exist since commit 46738b1317e1 (“ipv6: sr: add option to control lwtunnel support”), and commit 5559cea2d5aa (“ipv6: sr: fix possible use-after-free and null-ptr-deref”) replaced unregister_pernet_subsys() with genl_unregister_family() in this error path.
