CVE-2025-10456 (GCVE-0-2025-10456)

Vulnerability from cvelistv5 – Published: 2025-09-19 05:21 – Updated: 2025-09-19 11:57
VLAI?
Summary
A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.
Severity ?
7.1 (High)

CVE-2025-10457 (GCVE-0-2025-10457)

Vulnerability from cvelistv5 – Published: 2025-09-19 05:17 – Updated: 2025-09-19 13:09
VLAI?
Summary
The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.

CVE-2025-10456 (GCVE-0-2025-10456)

Vulnerability from nvd – Published: 2025-09-19 05:21 – Updated: 2025-09-19 11:57
VLAI?
Summary
A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.
Severity ?
7.1 (High)

Summary
The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.
