What it actually does
Uninitialized idiag_expires field in UDP socket diagnostic structures causes kernel memory bytes to be copied to userspace via netlink responses in inet_sk_diag_fill().
Why it matters to the business
Unprivileged local processes can read fragments of kernel memory, increasing risk of credential or address leakage that may aid further attacks on the system.
How an attack unfolds
An attacker invokes inet_diag or sock_diag netlink commands against UDP sockets; the kernel allocates a response buffer without initializing the expires field for UDP, then copies the entire structure to user space, leaking uninitialized bytes.
How to fix it
Apply the upstream fix that initializes idiag_expires in inet_sk_diag_fill() before returning diagnostic data; rebuild and deploy the patched kernel across all affected systems.
How to confirm the fix worked
Confirm the fix by inspecting the inet_sk_diag_fill() implementation to ensure idiag_expires is always set; test by repeatedly issuing UDP diag requests and verifying no uninitialized memory is present in responses.
Typical attack path
- Open a netlink socket to NETLINK_SOCK_DIAG
- Send an inet_diag request targeting UDP sockets
- Receive the response containing uninitialized kernel data
- Parse leaked bytes for useful kernel pointers or secrets
How to detect it
Review netlink audit records and system call traces for repeated sock_diag or inet_diag requests from unprivileged processes; inspect kernel logs for KMSAN or similar infoleak reports referencing inet_diag.
What your security team should do
- Prioritize kernel updates on all Linux systems exposing diag interfaces
- Restrict unprivileged access to NETLINK_SOCK_DIAG where possible via LSM or seccomp
- Monitor for local information disclosure attempts via netlink audit logs
The record
In the Linux kernel, the following vulnerability has been resolved: inet_diag: fix kernel-infoleak for UDP sockets KMSAN reported a kernel-infoleak [1], that can exploited by unpriv users. After analysis it turned out UDP was not initializing r->idiag_expires. Other users of inet_sk_diag_fill() might make the same mistake in the future, so fix this in inet_sk_diag_fill().
