EUVD-2026-81948

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: do not leak an hciconn when a second LE connect is rejected createleconncomplete decides whether the failed connection is still pending by comparing it against hcilookupleconnect, which returns the first LE connection ...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

There are use-after-free vulnerabilities in the net/bluetooth/l2capcore.c files, specifically in the l2capconnect and l2capleconnectreq functions. These vulnerabilities may allow code execution and the leakage of kernel memory remotely via Bluetooth. A remote attacker can execute code that leaks...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: fix UAF in l2cap le connect rsp l2cap le connect rsp obtains a channel via l2cap get chan by ident but neither holds a reference nor uses l2cap chan hold unless zero before locking and operating on it. A...

kernel: use-after-free in l2cap_connect and l2cap_le_connect_req in net/bluetooth/l2cap_core.c

A use-after-free flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol L2CAP, part of the Bluetooth stack in the l2capconnect and l2capleconnectreq functions. An attacker with physical access within the range of standard Bluetooth transmission could...

Vulnerability of the l2cap_connect and l2cap_le_connect_req functions (net/bluetooth/l2cap_core.c) in Linux kernel, allowing a hacker to execute arbitrary code

The vulnerability of the l2capconnect and l2capleconnectreq functions net/bluetooth/l2capcore.c in Linux kernel systems relates to the possibility of exploiting memory after it is freed. Exploiting this vulnerability could allow a remote attacker to execute arbitrary code...
