Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to v6.8
Description:
The issue is related to a memory leak in the Linux kernel due to a missing call to
page pool release page() between versions v5.9 to v5.14. The leak became visible in version v6.8 via a commit that catches page pool memory leaks. The vulnerability is associated with the xen-netfront module and the skb mark for recycle() function. Exploitation of this issue could allow an attacker to cause a denial of service.Recommendations:
To resolve the issue, update the Linux kernel to version v6.8 or later.
As a temporary workaround, consider restricting access to the
xen-netfront module to minimize the risk of exploitation.Exploit
