But that code does not require to handle interrupt allocation\nfailures. If the interrupt cannot be allocated then timer delivery fails\nand it either panics due to that or falls back to legacy mode.\n\nCure this by removing the panic wrapper around __add_pin_to_irq_node() and\nmaking mp_irqdomain_alloc() aware of the failure condition and handle it as\nany other failure in this function gracefully." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "arch/x86/kernel/apic/io_apic.c" ], "versions": [ { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "e479cb835feeb2abff97f25766e23b96a6eabe28", "status": "affected", "versionType": "git" }, { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "ec862cd843faa6f0e84a7a07362f2786446bf697", "status": "affected", "versionType": "git" }, { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "077e1b7cd521163ded545987bbbd389519aeed71", "status": "affected", "versionType": "git" }, { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "649a5c2ffae797ce792023a70e84c7fe4b6fb8e0", "status": "affected", "versionType": "git" }, { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "f17efbeb2922327ea01a9efa8829fea9a30e547d", "status": "affected", "versionType": "git" }, { "version": "49c7e60022912d10da88ba67e8eb2927f1143f6a", "lessThan": "830802a0fea8fb39d3dc9fb7d6b5581e1343eb1f", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "arch/x86/kernel/apic/io_apic.c" ], "versions": [ { "version": "4.2", "status": "affected" }, { "version": "0", "lessThan": "4.2", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.168", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.113", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.55", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.14", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.3", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "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": "4.2", "versionEndExcluding": "5.15.168" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.1.113" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.6.55" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.10.14" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.11.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/e479cb835feeb2abff97f25766e23b96a6eabe28" }, { "url": "https://git.kernel.org/stable/c/ec862cd843faa6f0e84a7a07362f2786446bf697" }, { "url": "https://git.kernel.org/stable/c/077e1b7cd521163ded545987bbbd389519aeed71" }, { "url": "https://git.kernel.org/stable/c/649a5c2ffae797ce792023a70e84c7fe4b6fb8e0" }, { "url": "https://git.kernel.org/stable/c/f17efbeb2922327ea01a9efa8829fea9a30e547d" }, { "url": "https://git.kernel.org/stable/c/830802a0fea8fb39d3dc9fb7d6b5581e1343eb1f" } ], "title": "x86/ioapic: Handle allocation failures gracefully", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-49927", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-10-22T13:39:34.506279Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-10-22T13:48:43.819Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:23:14.792Z" } } ] } }
