Name of the Vulnerable Software and Affected Versions Android for MSM (affected versions not specified) Firefox OS for MSM (affected versions not specified) QRD Android (affected versions not specified)

Description The issue is related to a possible buffer overflow in the linux kernel used by the mentioned Android releases. This occurs while incrementing the log buf of type uint64 t in the memcpy function. The log buf pointer can access memory beyond the size intended to store data after the pointer increment.

Recommendations For Android for MSM, consider restricting access to the memcpy function until a patch is available. For Firefox OS for MSM, avoid using the log buf pointer in sensitive operations to minimize the risk of exploitation. For QRD Android, as a temporary workaround, consider disabling the memcpy function for log buf operations until a fix is provided. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
