| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.43
Description
The vulnerability is related to the Linux kernel's UDP implementation, specifically in the
udp lib get port() function. The issue arises from the fact that the SOCK RCU FREE flag is set too early in the udp v[46] early demux() and sk lookup() functions, potentially leading to a small race window. This could allow an attacker to exploit the vulnerability, although the exact impact is not specified. The vulnerability was identified by syzkaller, a tool for finding bugs in the Linux kernel.Recommendations
To resolve the issue, update the Linux kernel to version 6.6.43 or later. This update includes the fix for the vulnerability, which sets the
SOCK RCU FREE flag earlier in the udp lib get port() function to prevent the race window.Exploit
