Title
net: ppp: Add bound checking for skb data on ppp_sync_txmung
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ppp: Add bound checking for skb data on ppp_sync_txmung
Ensure we have enough data in linear buffer from skb before accessing
initial bytes. This prevents potential out-of-bounds accesses
when processing short packets.
When ppp_sync_txmung receives an incoming package with an empty
payload:
(remote) gef➤ p *(struct pppoe_hdr *) (skb->head + skb->network_header)
$18 = {
type = 0x1,
ver = 0x1,
code = 0x0,
sid = 0x2,
length = 0x0,
tag = 0xffff8880371cdb96
}
from the skb struct (trimmed)
tail = 0x16,
end = 0x140,
head = 0xffff88803346f400 "4",
data = 0xffff88803346f416 ":\377",
truesize = 0x380,
len = 0x0,
data_len = 0x0,
mac_len = 0xe,
hdr_len = 0x0,
it is not safe to access data[2].

"value": "AV:N - The vulnerable function is reached from `ppp_input()` via `ppp_channel_bridge_input()`, which forwards remotely received PPP frames directly to the sync-tty channel\u0027s `start_xmit` before any length validation; the feeding channels include pppol2tp (UDP/IP) and pptp (GRE/IP), both routable across the internet on VPN concentrators. A remote peer sending a PPP payload shorter than 3 bytes triggers the read.\nAC:L - The trigger is fully deterministic and entirely attacker-controlled \u2014 emit one PPP frame with a zero-length or 1-2 byte payload; there is no race, no memory-layout requirement, and no state the attacker cannot influence.\nPR:N - PPPoE/PPTP/L2TP session establishment happens before any PPP-layer authentication (LCP/CHAP/PAP), so the malformed frame can be sent by an unauthenticated peer on an established but not-yet-authenticated session. No local account or capability is needed.\nUI:N - The out-of-bounds read occurs during normal packet transmit processing driven entirely by the attacker\u0027s inbound frame. No victim action is required.\nS:U - The impact is confined to the kernel\u0027s own security authority \u2014 a kernel-memory read within the same host. No VM, IOMMU, or sandbox boundary is crossed.\nC:L - The read is strictly bounded to at most 3 bytes past the valid skb data, and those bytes are never transmitted \u2014 they only influence the `islcp`/protocol-compression branches, giving an indirect oracle over adjacent (possibly uninitialized) kernel heap contents rather than an arbitrary read primitive.\nI:N - The defect is read-only; `skb_pull()` is length-checked via `skb_pull_inline()` so `skb-\u003elen` cannot underflow, and the subsequent `skb_push()` is guarded by an explicit `skb_headroom()` check, leaving no out-of-bounds write or corrupted state.\nA:H - The out-of-bounds access is syzbot-reproducible and trips KASAN/KMSAN, causing an oops or panic on sanitizer-enabled and hardened kernels (panic_on_oops/panic_on_warn), and it can be triggered repeatedly by an unauthenticated remote peer."

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.
