The list member\nof struct hid_input is at offset 0, so on an empty list list_entry()\nyields &hid->inputs itself and the following hidinput->input load reads\nan unrelated member of struct hid_device. dev is then a type-confused\npointer, and force-feedback init writes through it: each\nset_bit(FF_*, dev->ffbit) stores 8 bytes at dev + 192, past the end of\nthe object dev actually aliases, and input_ff_create() adds further\nwrites of a heap pointer and two function pointers.\n\nUntil hid-universal-pidff the only caller was hid_pidff_init() from\nusbhid, which runs under HID_CLAIMED_INPUT and therefore always has at\nleast one hid_input. universal_pidff_probe() starts the device with\nHID_CONNECT_DEFAULT & ~HID_CONNECT_FF and then calls\nhid_pidff_init_with_quirks() directly whenever the descriptor carries a\nPID usage page, bypassing that gate. A report descriptor whose only\napplication collection is on HID_UP_PID leaves hid->inputs empty while\nhid_connect() still succeeds through the hidraw claim, so probe reaches\nthe unguarded list_entry().\n\nThe write happens in the USB probe path, on the hotplug workqueue, so\nplugging in a malicious device is enough to trigger it; no attacker\nsoftware and no logged-in user are required. KASAN reports an 8-byte\nout-of-bounds write in hid_pidff_init_with_quirks() reached from\nuniversal_pidff_probe().\n\nCheck for an empty list before deriving dev and return -ENODEV, as the\nother HID force-feedback drivers already do. universal_pidff_probe()\npropagates the error and unwinds.\n\nDiscovered by XBOW, triaged by Baul Lee " } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/hid/usbhid/hid-pidff.c" ], "versions": [ { "version": "c1fde337b317f0a226de92803288741c30799eb0", "lessThan": "2e0471bf3ab2a6b7eedcc3b8a2a17286b6a9ae1a", "status": "affected", "versionType": "git" }, { "version": "f45f26a6b3e7260c129c7c6bb0ace63aeb7b3868", "lessThan": "ad9330f7e74a97842815a291a0d7389ed2f34504", "status": "affected", "versionType": "git" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "lessThan": "4529c03c3da8f91392cd630453452f569973f4cd", "status": "affected", "versionType": "git" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "lessThan": "d416eeb7d016d82af67c149d884bc6a9323c4ac7", "status": "affected", "versionType": "git" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "lessThan": "86b63adfa5e132beac4be72668fdf9128fe51d2e", "status": "affected", "versionType": "git" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "lessThan": "67bb1074e3d2d12fa059a9cc707e89398a4e4704", "status": "affected", "versionType": "git" }, { "version": "af9f2471dfe5a48384f5b7f021a673fbc741465e", "status": "affected", "versionType": "git" }, { "version": "b797352954eee6dc084cfaed0659dea60adfb484", "status": "affected", "versionType": "git" }, { "version": "6.6.88", "lessThan": "6.6.156", "status": "affected", "versionType": "semver" }, { "version": "6.12.24", "lessThan": "6.12.108", "status": "affected", "versionType": "semver" }, { "version": "6.13.12", "lessThan": "6.14", "status": "affected", "versionType": "semver" }, { "version": "6.14.3", "lessThan": "6.15", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/hid/usbhid/hid-pidff.c" ], "versions": [ { "version": "6.15", "status": "affected" }, { "version": "0", "lessThan": "6.15", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.156", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.108", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.47", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.1.11", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.2.1", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "7.3", "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": "6.6.88", "versionEndExcluding": "6.6.156" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.12.24", "versionEndExcluding": "6.12.108" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "6.18.47" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.1.11" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.2.1" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.14.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/2e0471bf3ab2a6b7eedcc3b8a2a17286b6a9ae1a" }, { "url": "https://git.kernel.org/stable/c/ad9330f7e74a97842815a291a0d7389ed2f34504" }, { "url": "https://git.kernel.org/stable/c/4529c03c3da8f91392cd630453452f569973f4cd" }, { "url": "https://git.kernel.org/stable/c/d416eeb7d016d82af67c149d884bc6a9323c4ac7" }, { "url": "https://git.kernel.org/stable/c/86b63adfa5e132beac4be72668fdf9128fe51d2e" }, { "url": "https://git.kernel.org/stable/c/67bb1074e3d2d12fa059a9cc707e89398a4e4704" } ], "title": "HID: pidff: fix OOB write when hid->inputs is empty", "x_generator": { "engine": "bippy-1.2.0" } } } }
