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...

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...
