CVE-2024-56601

net: inet: do not leave a dangling sk pointer in inet_create()

State: Published
Severity: 7.8 High
Published: Dec 27, 2024
Updated: Oct 15, 2026
Reserved: Dec 27, 2024

Description

In the Linux kernel, the following vulnerability has been resolved:

net: inet: do not leave a dangling sk pointer in inet_create()

sock_init_data() attaches the allocated sk object to the provided sock object. If inet_create() fails later, the sk object is freed, but the sock object retains the dangling pointer, which may create use-after-free later.

Clear the sk pointer in the sock object on error.
