kernel: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create()

A user-after-free vulnerability was found in the linux kernel. sockinitdata attaches the allocated sk object to the provided sock object. If ieee802154create fails later, the allocated sk object is freed, but the dangling pointer remains in the provided sock object, leading to a crash and loss of...

kernel: hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer

In the Linux kernel, the following vulnerability has been resolved: hvsock: Initializing vsk-trans to NULL to prevent a dangling pointer When hvs is released, there is a possibility that vsk-trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by...
