Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a Bluetooth L2CAP protocol post-release reuse issue in l2capconnect...

PT-2024-8239

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58 Description: The issue is related to a use-after-free vulnerability in the l2cap connect function within the Linux kernel's Bluetooth L2CAP implementation. This vulnerability can be exploited to impact th...

Linux Bluetooth Kernel L2CAP Buffer Overflow DoS

The vulnerability of the l2capconnect function in the net/bluetooth/l2capcore.c module of the Linux operating system’s Bluetooth kernel implementation is related to the reallocation of previously freed memory due to concurrent access to resources. Exploiting this vulnerability could allow an...

DEBIAN-CVE-2024-36013

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix slab-use-after-free in l2capconnect Extend a critical section to prevent chan from early freeing. Also make the l2capconnect return type void. Nothing is using the returned value but it is ugly to return 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...
