No network-facing service parses attacker data to reach this code.\nAC:L - The attacker fully controls both inputs to the faulty index computation \u2014 a program that uses exactly 512 bytes of stack plus a single `may_goto` instruction deterministically yields `interpreters[16]` on every attempt. No race, timing, or uncontrolled memory-layout condition is involved.\nPR:L - Loading a BPF program requires only an unprivileged local account on systems where `kernel.unprivileged_bpf_disabled=0` (socket-filter/cgroup_skb types load without CAP_BPF), and `may_goto` has no additional capability gate in the verifier. No root or administrative privilege is needed.\nUI:N - The attacker loads and triggers the BPF program entirely on their own; no victim action, mount, or file open is required.\nS:U - The out-of-bounds access and the resulting corrupted control flow are confined to the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - An out-of-bounds read past `interpreters[]` yields a function pointer that is then invoked, causing the BPF interpreter to execute uncontrolled memory as bytecode with unbounded `BPF_LDX` loads, which can be leveraged to disclose arbitrary kernel memory.\nI:H - The wrongly-typed indirect call runs `___bpf_prog_run()` over an uninitialized instruction pointer, so `BPF_STX`/`BPF_ST` stores and `BPF_CALL` dispatches operate on unvalidated addresses \u2014 a memory-corruption and control-flow-hijack primitive.\nA:H - In the common case the bogus interpreter entry hits `BUG_ON(1)` on an unknown opcode or faults on a wild pointer, producing a kernel oops/panic that any local user can trigger on demand."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["kernel/bpf/core.c", "kernel/bpf/verifier.c"], "versions": [{"version": "011832b97b311bb9e3c27945bc0d1089a14209c9", "lessThan": "19e6817f84000d0b06f09fd69ebd56217842c122", "status": "affected", "versionType": "git"}, {"version": "011832b97b311bb9e3c27945bc0d1089a14209c9", "lessThan": "4524b7febdd55fb99ae2e1f48db64019fa69e643", "status": "affected", "versionType": "git"}, {"version": "011832b97b311bb9e3c27945bc0d1089a14209c9", "lessThan": "1a86ae57b2600e5749f5f674e9d4296ac00c69a8", "status": "affected", "versionType": "git"}, {"version": "011832b97b311bb9e3c27945bc0d1089a14209c9", "lessThan": "6ebc5030e0c5a698f1dd9a6684cddf6ccaed64a0", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["kernel/bpf/core.c", "kernel/bpf/verifier.c"], "versions": [{"version": "6.9", "status": "affected"}, {"version": "0", "lessThan": "6.9", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.23", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.13.11", "lessThanOrEqual": "6.13.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.14.2", "lessThanOrEqual": "6.14.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.15", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.12.23"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.13.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.14.2"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.15"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/19e6817f84000d0b06f09fd69ebd56217842c122"}, {"url": "https://git.kernel.org/stable/c/4524b7febdd55fb99ae2e1f48db64019fa69e643"}, {"url": "https://git.kernel.org/stable/c/1a86ae57b2600e5749f5f674e9d4296ac00c69a8"}, {"url": "https://git.kernel.org/stable/c/6ebc5030e0c5a698f1dd9a6684cddf6ccaed64a0"}], "title": "bpf: Fix array bounds error with may_goto", "x_generator": {"engine": "bippy-1.2.0"}}}}
