Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a race condition in the
netpoll owner active() function, which can lead to a data-race in net rx action and netpoll send skb. This happens because netpoll owner active() needs to check if the current CPU is the owner of the lock, touching napi->poll owner non-atomically. The ->poll owner field contains the current CPU holding the lock. To fix this, an atomic read should be used to check if the poll owner is the current CPU.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
