malicious nearby device to determine the passkey used to complete the
pairing, or potentially pair itself instead.

An unsigned to signed integer conversion flaw in the virtual file system
implementation could lead to a system crash. A local attacker could use
this flaw to execute arbitrary code or cause a denial-of-service.
