[PATCH net-next v3 7/9] net: inet6: do not leave a dangling sk pointer in inet6_create()

2024-10-14 Thread Ignat Korchagin
sock_init_data() attaches the allocated sk pointer to the provided sock object. If inet6_create() fails later, the sk object is released, but the sock object retains the dangling sk pointer, which may cause use-after-free later. Clear the sock sk pointer on error. Signed-off-by: Ignat Korchagin
