CVE-2024-56602: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create()
First published: Fri Dec 27 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create() sock_init_data() attaches the allocated sk object to the provided sock object. If ieee802154_create() fails later, the allocated sk object is freed, but the dangling pointer remains in the provided sock object, which may allow use-after-free. Clear the sk pointer in the sock object on error.
