Title
bpf: Fix a sdiv overflow issue
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a sdiv overflow issue Zac Ecob reported a problem where a bpf program may cause kernel crash due to the following error: Oops: divide error: 0000 [#1] PREEMPT SMP KASAN PTI The failure is due to the below signed divide: LLONG_MIN/-1 where LLONG_MIN equals to -9,223,372,036,854,775,808. LLONG_MIN/-1 is supposed to give a positive number 9,223,372,036,854,775,808, but it is impossible since for 64-bit system, the maximum positive number is 9,223,372,036,854,775,807. On x86_64, LLONG_MIN/-1 will cause a kernel exception. On arm64, the result for LLONG_MIN/-1 is LLONG_MIN. Further investigation found all the following sdiv/smod cases may trigger an exception when bpf program is running on x86_64 platform: - LLONG_MIN/-1 for 64bit operation - INT_MIN/-1 for 32bit operation - LLONG_MIN%-1 for 64bit operation - INT_MIN%-1 for 32bit operation where -1 can be an immediate or in a register. On arm64, there are no exceptions: - LLONG_MIN/-1 = LLONG_MIN - INT_MIN/-1 = INT_MIN - LLONG_MIN%-1 = 0 - INT_MIN%-1 = 0 where -1 can be an immediate or in a register. Insn patching is needed to handle the above cases and the patched codes produced results aligned with above arm64 result. The below are pseudo codes to handle sdiv/smod exceptions including both divisor -1 and divisor 0 and the divisor is stored in a register. sdiv: tmp = rX tmp += 1 /* [-1, 0] -> [0, 1] if tmp >(unsigned) 1 goto L2 if tmp == 0 goto L1 rY = 0 L1: rY = -rY; goto L3 L2: rY /= rX L3: smod: tmp = rX tmp += 1 /* [-1, 0] -> [0, 1] if tmp >(unsigned) 1 goto L1 if tmp == 1 (is64 ? goto L2 : goto L3) rY = 0; goto L2 L1: rY %= rX L2: goto L4 // only when !is64 L3: wY = wY // only when !is64 L4: [1] https://lore.kernel.org/bpf/tPJLTEh7S_DxFEqAI2Ji5MBSoZVg7_G-Py2iaZpAaWtM961fFTWtsnlzwvTbzBzaUzwQAoNATXKUlt0LZOFgnDcIyKCswAnAGdUF3LBrhGQ=@protonmail.com/

Se supone que LLONG_MIN/-1 da un n\u00famero positivo 9.223.372.036.854.775.808, pero es imposible ya que para sistemas de 64 bits, el n\u00famero positivo m\u00e1ximo es 9.223.372.036.854.775.807. En x86_64, LLONG_MIN/-1 provocar\u00e1 una excepci\u00f3n del kernel. En arm64, el resultado para LLONG_MIN/-1 es LLONG_MIN. Una investigaci\u00f3n m\u00e1s profunda encontr\u00f3 que todos los siguientes casos de sdiv/smod pueden activar una excepci\u00f3n cuando el programa bpf se ejecuta en la plataforma x86_64: - LLONG_MIN/-1 para operaci\u00f3n de 64 bits - INT_MIN/-1 para operaci\u00f3n de 32 bits - LLONG_MIN%-1 para operaci\u00f3n de 64 bits - INT_MIN%-1 para operaci\u00f3n de 32 bits donde -1 puede ser inmediato o en un registro. En arm64, no hay excepciones: - LLONG_MIN/-1 = LLONG_MIN - INT_MIN/-1 = INT_MIN - LLONG_MIN%-1 = 0 - INT_MIN%-1 = 0 donde -1 puede ser inmediato o en un registro. Se necesita aplicar un parche a Insn para manejar los casos anteriores y los c\u00f3digos parcheados produjeron resultados alineados con el resultado de arm64 anterior. Los siguientes son pseudoc\u00f3digos para manejar excepciones sdiv/smod incluyendo tanto el divisor -1 como el divisor 0 y el divisor se almacena en un registro. sdiv: tmp = rX tmp += 1 /* [-1, 0] -\u0026gt; [0, 1] if tmp \u0026gt;(unsigned) 1 goto L2 if tmp == 0 goto L1 rY = 0 L1: rY = -rY; goto L3 L2: rY /= rX L3: smod: tmp = rX tmp += 1 /* [-1, 0] -\u0026gt; [0, 1] if tmp \u0026gt;(unsigned) 1 goto L1 if tmp == 1 (is64 ? goto L2 : goto L3) rY = 0; goto L2 L1: rY %= rX L2: goto L4 // solo cuando !is64 L3: wY = wY // solo cuando !is64 L4: [1] https://lore.kernel.org/bpf/tPJLTEh7S_DxFEqAI2Ji5MBSoZVg7_G-Py2iaZpAaWtM961fFTWtsnlzwvTbzBzaUzwQAoNATXKUlt0LZOFgnDcIyKCswAnAGdUF3LBrhGQ=@protonmail.com/\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"kernel/bpf/verifier.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"ec0e2da95f72d4a46050a4d994e4fe471474fd80\",\"lessThan\":\"4902a6a0dc593c82055fc8c9ada371bafe26c9cc\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ec0e2da95f72d4a46050a4d994e4fe471474fd80\",\"lessThan\":\"d22e45a369afc7c28f11acfa5b5e8e478227ca5d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ec0e2da95f72d4a46050a4d994e4fe471474fd80\",\"lessThan\":\"7dd34d7b7dcf9309fc6224caf4dd5b35bedddcb7\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"kernel/bpf/verifier.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"6.6\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"6.6\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.10.14\",\"lessThanOrEqual\":\"6.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.11.3\",\"lessThanOrEqual\":\"6.11.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}],\"ssvcV203\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"ssvcData\":{\"timestamp\":\"2024-10-22T13:44:44.632925Z\",\"id\":\"CVE-2024-49888\",\"options\":[{\"exploitation\":\"none\"},{\"automatable\":\"no\"},{\"technicalImpact\":\"partial\"}],\"role\":\"CISA Coordinator\",\"version\":\"2.0.3\"}}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-190\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"6.10.14\",\"matchCriteriaId\":\"652638C5-5F25-4DF3-AD42-DD3252A97152\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.11\",\"versionEndExcluding\":\"6.11.3\",\"matchCriteriaId\":\"54D9C704-D679-41A7-9C40-10A6B1E7FFE9\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/4902a6a0dc593c82055fc8c9ada371bafe26c9cc\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/7dd34d7b7dcf9309fc6224caf4dd5b35bedddcb7\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/d22e45a369afc7c28f11acfa5b5e8e478227ca5d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}",
