Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to the version that includes the fix for this issue
Description
A vulnerability in the Linux kernel has been resolved, which prevented multiple calls in a row to napi disable, causing a hang. The issue occurred when two or more threads called veth pool store through writing to /sys/devices/vio/30000002/pool*/*. This could be easily reproduced with a shell script. The fix involves using rtnl mutex to synchronize veth pool store with itself, ibmveth close, and ibmveth open.
Recommendations
To resolve this issue, update to a Linux kernel version that includes the fix for this vulnerability.
As a temporary workaround, consider restricting access to the /sys/devices/vio/30000002/pool*/* path to minimize the risk of exploitation.
