CVSS 7.099999904632568 HIGH
A flaw was found in the Linux kernel, specifically within its Bluetooth Synchronous Connection-Oriented (SCO) component. This vulnerability occurs due to race conditions when multiple connection attempts are made simultaneously on the same Bluetooth socket. This can lead to a use-after-free error, where the system attempts to use memory that has already been released. Exploitation of this flaw could result in system instability, causing the system to crash or become unresponsive, and potentially lead to a denial of service.
