For an index\nof 32..127 the test_and_set_bit()/test_and_clear_bit() is an\nout-of-bounds single-bit read-modify-write past the array. core_effects[]\nis the second-to-last member of struct iforce, so the write lands in the\ntrailing members and beyond the embedding kzalloc()'d iforce_serio /\niforce_usb object.\n\ndata[1] is unvalidated device payload on both transports (the USB\ninterrupt endpoint and serio), and the status path is not gated on force\nfeedback being present, so a malicious or counterfeit device can set or\nclear a bit at an attacker-chosen offset past the object.\n\nReject an out-of-range index instead of indexing with it. Bound against\nthe array dimension IFORCE_EFFECTS_MAX rather than dev->ff->max_effects so\nthe check guarantees memory safety regardless of how many effects the\ndevice registered. A legitimate \"effect started/stopped\" status always\ncarries an index below IFORCE_EFFECTS_MAX, so well-formed devices are\nunaffected; the neighbouring mark_core_as_ready() loop is already bounded\nand is left untouched." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git",
