CVE-2024-56601 (GCVE-0-2024-56601)

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

No race and no attacker-uncontrollable precondition is involved.\nPR:L - Any ordinary unprivileged local user can call `socket()`; the ICMP-datagram and MPTCP paths involve no capability check at all, and the `SOCK_RAW` variant\u0027s `CAP_NET_RAW` is `ns_capable(net-\u003euser_ns, ...)`, obtainable via `unshare -Urn`.\nUI:N - The attacker triggers the whole sequence from their own process with a single syscall; no action by any other user or administrator is needed.\nS:U - The dangling pointer and any resulting corruption stay within the kernel\u0027s own security authority \u2014 this is a standard local kernel memory-safety issue with no VM, IOMMU, or sandbox boundary crossed.\nC:H - `sock-\u003esk` is left pointing at a `struct sock` already freed by `sk_common_release()`; any subsequent dereference reads reclaimed slab memory whose contents the attacker can spray, yielding disclosure of kernel data and pointers.\nI:H - A use-after-free on a `struct sock` \u2014 an object dense with function pointers (`sk_destruct`, `sk_backlog_rcv`, `sk_prot` ops) \u2014 gives an attacker who reclaims the freed slab a write/control-flow-hijack primitive, so integrity impact must be treated as High.\nA:H - Dereferencing the stale `sk` pointer corrupts or faults on freed memory, producing a kernel oops or panic; the trigger is a single unprivileged syscall that can be repeated at will."
