Details

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.

Severity ?
7.8 (High)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
