"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()\n\nIn the parse_adv_monitor_pattern() function, the value of\nthe 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).\nThe size of the 'value' array in the mgmt_adv_pattern structure is 31.\nIf the value of 'pattern[i].length' is set in the user space\nand exceeds 31, the 'patterns[i].value' array can be accessed\nout of bound when copied.\n\nIncreasing the size of the 'value' array in\nthe 'mgmt_adv_pattern' structure will break the userspace.\nConsidering this, and to avoid OOB access revert the limits for 'offset'\nand 'length' back to the value of HCI_MAX_AD_LENGTH.\n\nFound by InfoTeCS on behalf of Linux Verification Center\n(linuxtesting.org) with SVACE."
