Title
vsock: Fix transport_* TOCTOU
Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: Fix transport_* TOCTOU
Transport assignment may race with module unload. Protect new_transport
from becoming a stale pointer.
This also takes care of an insecure call in vsock_use_local_transport();
add a lockdep assert.
BUG: unable to handle page fault for address: fffffbfff8056000

"value": "AV:L - The vulnerable code is reached through the AF_VSOCK socket API \u2014 `socket(AF_VSOCK, SOCK_DGRAM)` and `connect()` \u2014 which requires a local execution context on the target system. Per kernel scoring convention vsock is treated as a local attack vector even though the listener path is also driven by peer packets.\nAC:H - The attacker fully controls one side of the race (a tight `connect()`/`socket()` loop, and can widen the window via transport reassignment through `release()`/`destruct()`), but the other side requires a concurrent vsock transport module unload, which is gated by `capable(CAP_SYS_MODULE)` in the init user namespace and therefore cannot be induced by the attacker at will.\nPR:L - Creating an AF_VSOCK socket and calling connect() requires no capabilities whatsoever \u2014 there is no `capable()` gate on `vsock_create()` or `vsock_connect()` \u2014 so any unprivileged local user, including one inside an unprivileged container, can drive the racing side.\nUI:N - The attacker\u0027s exploitation path is pure syscall activity with no victim action required; the administrative module unload is a system-state precondition already accounted for in Attack Complexity and is not double-counted here.\nS:U - The stale-pointer dereference, wild write and indirect calls all occur in the host kernel\u0027s own security authority, which is the same authority that manages the vsock socket. This is standard kernel-level compromise with no crossing of a VM, IOMMU or sandbox boundary.\nC:H - This is a use-after-free on freed module memory: `new_transport-\u003emodule` and the transport\u0027s function pointers are read from a region that has been released by `execmem_free()` and can be reallocated by a subsequent module load. Combined with the indirect calls through those stale pointers, this yields arbitrary kernel memory disclosure.\nI:H - `try_module_get()` performs `atomic_inc_not_zero()` on a `struct module *` read out of freed memory, giving an increment-write through an attacker-influenceable address, and `new_transport-\u003eseqpacket_allow()`/`-\u003einit()` are indirect calls through function pointers read from that same freed region \u2014 a control-flow hijack primitive.\nA:H - The bug is demonstrated by an unrecoverable oops \u2014 \"BUG: unable to handle page fault for address: fffffbfff8056000\" at `vsock_assign_transport+0x366` \u2014 and any use-after-free of this kind reliably panics the kernel even when not fully weaponized."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
