- Summary
- CVE-2025-38617 affecting package kernel for versions less than 6.6.104.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net/packet: fix a race in packetsetring() and packet_notifier()
When packetsetring() releases po->bindlock, another thread can run packetnotifier() and process an NETDEV_UP event.
This race and the fix are both similar to that of commit 15fe076edea7 ("net/packet: fix a race in packetbind() and packetnotifier()").
There too the packetnotifier NETDEVUP event managed to run while a po->bind_lock critical section had to be temporarily released. And the fix was similarly to temporarily set po->num to zero to keep the socket unhooked until the lock is retaken.
The po->bindlock in packetsetring and packetnotifier precede the introduction of git history.
