Vulnerability from github – Published: 2024-02-21 15:30 – Updated: 2024-03-15 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

net: tls: fix use-after-free with partial reads and async decrypt

tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when we try to read from the partially-read skb.

Severity

7.8 (High)

Per kernel scoring guidance, kTLS bugs triggered by remote peer data are Network.\nAC:L - There is no race to win \u2014 the async completion callback frees the pages before process_rx_list() reads them, deterministically. The required preconditions are the default on mainstream deployments (TLS 1.2 + generic-gcm-aesni, which the SIMD wrapper always registers with CRYPTO_ALG_ASYNC) and the remaining one, a partial read, is forced at will by the peer sending oversized records.\nPR:N - The attacker is the remote TLS peer, which holds no privileges or account on the target system \u2014 any client that completes an anonymous TLS handshake with a kTLS-offloading server (or any malicious server a kTLS client connects to) can drive the bug. No local credentials are involved anywhere on the path.\nUI:N - The only local behavior required is an application calling recvmsg() on its kTLS socket with a buffer smaller than the incoming record, which is ordinary, continuous operation of any TLS-consuming server or client. No victim performs any special action.\nS:U - The corruption is confined to kernel memory managed by the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is a standard in-kernel memory-safety issue.\nC:H - process_rx_list() copies the contents of already-freed pages directly into the userspace receive buffer, and the partial-read nature leaves the stale skb on rx_list so the leak repeats on later recvmsg() calls with a wide reallocation window. Attacker-driven spraying can place other sockets\u0027 plaintext, page-cache data, or slab contents into those pages, yielding a repeatable kernel memory disclosure primitive.\nI:H - Beyond the read, skb_release_data() issues a second put_page() on pages that have since been reallocated, dropping a live page\u0027s refcount to zero and freeing memory owned by an unrelated allocation. This cross-owner page use-after-free is a well-established route to arbitrary write and control-flow hijack via reuse as slab or page-table memory.\nA:H - The page refcount underflow triggers bad_page()/VM_BUG_ON_PAGE and corrupts the buddy allocator, and reading or reusing freed pages oopses immediately under KASAN or page poisoning. A remote peer can trigger this repeatedly, reliably panicking the machine."

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.
