Summary
Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: MGMT: Fix OOB access in parseadvmonitor_pattern()

In the parseadvmonitorpattern() function, the value of the 'length' variable is currently limited to HCIMAXEXTADLENGTH(251). The size of the 'value' array in the mgmtadv_pattern structure is 31. If the value of 'pattern[i].length' is set in the user space and exceeds 31, the 'patterns[i].value' array can be accessed out of bound when copied.

Increasing the size of the 'value' array in the 'mgmtadvpattern' structure will break the userspace. Considering this, and to avoid OOB access revert the limits for 'offset' and 'length' back to the value of HCIMAXAD_LENGTH.

Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
