kernel: Bluetooth: SMP: force responder MITM requirements before building the pairing response

A flaw was found in the Linux kernel's Bluetooth Security Manager Protocol SMP. An attacker could exploit this vulnerability during the Bluetooth pairing process by manipulating authentication requirements. This could lead to the selection of a weaker pairing method than intended, potentially...

kernel: Bluetooth: HIDP: fix missing length checks in hidp_input_report()

A flaw was found in the Linux kernel's Bluetooth Human Interface Device Protocol HIDP. A remote attacker, by sending specially crafted truncated packets from a paired Bluetooth device, could trigger an out-of-bounds read in the hidpinputreport function. This vulnerability may lead to unintended...

kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition in the hidpsessionthread can lead to a use-after-free vulnerability. This occurs when a timer is active while its deletion function is called, causing memory to be accessed after it has been freed. A local attacker could...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...

kernel: Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. When a device receives a connection response with an already-assigned destination Channel Identifier CID, the system may crash. This occurs because the kernel's procedure for...

Some cheap smart glasses are a security disaster

Apart from the privacy concerns around smart glasses, researchers have found that some cheap brands come with barely any security at all. ABC Australia reports that researchers from NSB Cyber and Abstract Shield tested two inexpensive pairs, costing A$60 and A$110 around US$42 and US$78, and foun...
