| 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 6.12.0-rc3-custom-gd95d9a31aceb
Description:
The issue is related to a suspicious RCU usage warning in the
ip tunnel find() function. The per-netns IP tunnel hash table is protected by the RTNL mutex, and ip tunnel find() is only called from the control path where the mutex is taken. A lockdep expression has been added to hlist for each entry rcu() in ip tunnel find() to validate that the mutex is held and to silence the suspicious RCU usage warning.Recommendations:
To resolve the issue, update to a version of the Linux kernel that includes the fix for the suspicious RCU usage warning in
ip tunnel find().
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
