| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition between
netvsc probe and netvsc remove has been resolved in the Linux kernel. The issue occurred when napi disable was called for all channels, including subchannels, without confirming if they were enabled or not. This caused hv netvsc to get hung at napi disable when netvsc probe() finished running but nvdev->subchan work had not started yet. The fix ensures that napi disable() is not called for non-enabled NAPI structs. netif napi del() is still necessary for these non-enabled NAPI structs for cleanup purposes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
