CVE-2026-72336

A flaw was found in the Linux kernel's Bluetooth 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks component. A race condition exists where an L2CAP Logical Link Control and Adaptation Protocol connection is accessed after its protection is dropped, allowing it to be deallocated...

CVE-2026-72333

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol implementation. A remote attacker, by continuously streaming data to a host, can trigger an identifier ident leak. This occurs because identifiers for certain commands, such as L2CAPLECREDITS, are...

The vulnerability in the `net/bluetooth/l2cap_core.c` component of the Linux operating system allows a hacker to gain access to confidential data and compromise its integrity.

The vulnerability of the net/bluetooth/l2capcore.c component in the Linux operating system is related to incorrect checking of the data size at the input stage. Exploiting this vulnerability can allow an attacker to gain access to confidential data and compromise its integrity...
