kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c

A use-after-free flaw was found in the Linux kernel’s L2CAP bluetooth functionality in how a user triggers a race condition by two malicious flows in the L2CAP bluetooth packets. This flaw allows a local or bluetooth connection user to crash the system or potentially escalate privileges...

SUSE CVE-2012-6544

The Bluetooth protocol stack in the Linux kernel before 3.6 does not properly initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application that targets the 1 L2CAP or 2 HCI implementation...

SUSE CVE-2021-27861

Layer 2 network filtering capabilities such as IPv6 RA guard can be bypassed using LLC/SNAP headers with invalid length and optionally VLAN0 headers...

The vulnerability of the LLC subsystem in the Linux kernel, related to insufficient validation of input data, allows a hacker to trigger a service failure.

The vulnerability of the LLC subsystem in the Linux kernel is related to insufficient validation of input data. Exploiting this vulnerability can allow an attacker to cause a service failure...
