Description OSIDB Bzimport 2024-12-27 15:03:23 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: inet6: do not leave a dangling sk pointer in inet6_create()

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.
