Upgrade torvalds/linux to version 5.10.258, 5.15.209, 6.1.175, 6.6.136, 6.12.83, 6.18.24, 6.19.14 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the l2tp_xmit_core process. An attacker can cause unintended disclosure of information by sending oversized PPPoL2TP packets with UDP encapsulation, which leads to an overflow of the 16-bit UDP length field and results in trimmed data being sent over the network.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
