Overview

Affected versions of this package are vulnerable to Information Exposure in the snoop_file_read process. An attacker can access sensitive kernel memory by triggering concurrent access to the kfifo buffer between the IRQ handler and file reader, leading to a usercopy operation that exposes kernel memory contents.

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
