A race condition was found in the Linux kernel's net/bluetooth device driver in conn_info_{min,max}_age_set() function. This can result in integrity overflow issue, possibly leading to bluetooth connection abnormality or denial of service.
Solution:
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
