Overview

Affected versions of this package are vulnerable to Information Exposure in the bounce_error_event process. An attacker can obtain sensitive kernel heap addresses by triggering a bounce error event that is delivered to a user client, causing the kernel pointer to be exposed to userspace through the fixed-length branch of snd_seq_read().

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
