"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: logitech-dj: Fix maxfield check in DJ short report validation\n\nCommit b6a57912854e (\"HID: logitech-dj: Prevent REPORT_ID_DJ_SHORT\nrelated user initiated OOB write\") added validation for the DJ short\noutput report, but the error path dereferences rep->field[0] even when\nrep->maxfield is zero.\n\nCommit 8b9a097eb2fc (\"HID: logitech-dj: fix wrong detection of bad\nDJ_SHORT output report\") made the check conditional on rep being present,\nbut a crafted descriptor can still create report ID 0x20 with only padding\noutput items. hid-core registers the report, ignores the padding field,\nand leaves rep->maxfield as zero.\n\nIn that case the validation enters the rep->maxfield < 1 branch and then\ndereferences rep->field[0]->report_count while printing the error message,\ncausing a NULL pointer dereference during probe. This is reproducible with\nuhid by emulating a Logitech receiver with a padding-only DJ short output\nreport:\n\n BUG: KASAN: null-ptr-deref in logi_dj_probe+0xb1/0x754 [hid_logitech_dj]\n Read of size 4 at addr 0000000000000028 by task kworker/4:1/129\n ...\n Call Trace:\n logi_dj_probe+0xb1/0x754 [hid_logitech_dj]\n hid_device_probe+0x329/0x3f0 [hid]\n really_probe+0x162/0x570\n __device_attach+0x137/0x2c0\n bus_probe_device+0x38/0xc0\n device_add+0xa56/0xce0\n hid_add_device+0x19c/0x280 [hid]\n uhid_device_add_worker+0x2c/0xb0 [uhid]\n\nReject the zero-field report before printing the field report_count."
