CVE-2020-0553

Vulnerability

A out-of-bounds read vulnerability exists in the kernel mode driver for some Intel(R) Wireless Bluetooth(R) products running on Windows* 10 [1]. The flaw is triggered when the driver incorrectly handles certain inputs, leading to a read beyond the intended buffer boundaries. The specific driver versions may be inferred from the advisory, which covers affected Intel Wireless Bluetooth products where an update is required.

Exploitation

An attacker must have local access to the system and possess elevated (privileged) user permissions [1]. No user interaction beyond the attacker's own actions is required; the attacker can trigger the out-of-bounds read by sending crafted IOCTL requests to the vulnerable driver.

Impact

Successful exploitation allows an attacker to read sensitive kernel memory, leading to information disclosure [1]. This disclosure may expose system or user data that could further compromise the system. The attacker does not gain code execution or direct privilege escalation from this vulnerability alone.

Mitigation

Intel released firmware and driver updates to address the vulnerability, as detailed in Intel-SA-00337 [1]. Affected users should apply the updated drivers provided by Intel to their Windows 10 systems. No workaround is available besides applying the patch.
