there is no race, no timing window, and no dependency on memory layout or victim state.\nPR:N - No credentials, no socket, and no local account are needed — the PTP classifier hook runs on every received frame before any port/permission check.\nUI:N - The vulnerable path executes automatically during packet receive processing with no action from any local user.\nS:U - The fault occurs and is contained within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The bug is a read of a fixed low address (NULL+30) whose value is only used as a sequence-ID comparison key; no kernel memory contents are disclosed to the attacker.\nI:N - Nothing is written and no adjacent structure is corrupted — the dereference faults before any state is modified.\nA:H - A NULL dereference in NET_RX softirq context produces an oops in interrupt context, panicking the machine, and it can be re-triggered at will with a single unauthenticated packet." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/phy/micrel.c" ], "versions": [ { "version": "ece19502834d84ece2e056db28257ca2aa6e4d48", "lessThan": "10608161696c2768f53426642f78a42bcaaa53e8", "status": "affected", "versionType": "git" }, { "version": "ece19502834d84ece2e056db28257ca2aa6e4d48", "lessThan": "95c1016a2d92c4c28a9d1b6d09859c00b19c0ea4", "status": "affected", "versionType": "git" }, { "version": "ece19502834d84ece2e056db28257ca2aa6e4d48", "lessThan": "49767b0df276f12e3e7184601e09ee7430e252dc", "status": "affected", "versionType": "git" }, { "version": "ece19502834d84ece2e056db28257ca2aa6e4d48", "lessThan": "96c155943a703f0655c0c4cab540f67055960e91", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/phy/micrel.c" ], "versions": [ { "version": "5.18", "status": "affected" }, { "version": "0", "lessThan": "5.18", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.85", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.26", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.5", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "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": "5.18", "versionEndExcluding": "6.1.85" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.6.26" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.8.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/10608161696c2768f53426642f78a42bcaaa53e8" }, { "url": "https://git.kernel.org/stable/c/95c1016a2d92c4c28a9d1b6d09859c00b19c0ea4" }, { "url": "https://git.kernel.org/stable/c/49767b0df276f12e3e7184601e09ee7430e252dc" }, { "url": "https://git.kernel.org/stable/c/96c155943a703f0655c0c4cab540f67055960e91" } ], "title": "net: phy: micrel: Fix potential null pointer dereference", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-06-17T17:38:45.513318Z", "id": "CVE-2024-35891", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-17T17:41:32.553Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T03:21:48.811Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/10608161696c2768f53426642f78a42bcaaa53e8", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/95c1016a2d92c4c28a9d1b6d09859c00b19c0ea4", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/49767b0df276f12e3e7184601e09ee7430e252dc", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/96c155943a703f0655c0c4cab540f67055960e91", "tags": [ "x_transferred" ] } ] } ] } }
