UBUNTU-CVE-2024-57933: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: What conditions are required to trigger the crash?

A local attacker needs low privileges and must be able to enable or disable XSK pools while the affected GVE network interface is down. The crash occurs because the RX queue pointer can be NULL when queues do not exist.

Q: Can normal XSK pool registration still occur after this condition?

Yes. When queue creation is deferred because the interface is down, XSK pool registration occurs during the next interface-up event.

Q: What race condition does the fix address beyond pool enablement and disablement?

The fix also guards xsk_wakeup against queues disappearing while it executes. It uses the GVE_PRIV_FLAGS_NAPI_ENABLED flag to synchronize with queue teardown and the synchronize_net() call in gve_turndown.

Updated

In the Linux kernel, the following vulnerability has been resolved: gve: guard XSK operations on the existence of queues This patch predicates the enabling and disabling of XSK pools on the existence of queues. As it stands, if the interface is down, disabling or enabling XSK pools would result in a crash, as the RX queue pointer would be NULL. XSK pool registration will occur as part of the next interface up. Similarly, xskwakeup needs be guarded against queues disappearing while the function is executing, so a check against the GVEPRIVFLAGSNAPIENABLED flag is added to synchronize with the disabling of the bit and the synchronizenet() in gveturndown.

Frequently Asked Questions

What conditions are required to trigger the crash?

A local attacker needs low privileges and must be able to enable or disable XSK pools while the affected GVE network interface is down. The crash occurs because the RX queue pointer can be NULL when queues do not exist.

Can normal XSK pool registration still occur after this condition?

Yes. When queue creation is deferred because the interface is down, XSK pool registration occurs during the next interface-up event.

What race condition does the fix address beyond pool enablement and disablement?

The fix also guards xsk_wakeup against queues disappearing while it executes. It uses the GVE_PRIV_FLAGS_NAPI_ENABLED flag to synchronize with queue teardown and the synchronize_net() call in gve_turndown.
