CVE-2021-46947

CVE-2021-46947 is a Linux kernel issue in the sfc (Solarflare) driver where efx->xdp_tx_queue_count can reflect too many uninitialized slots after probing, risking a NULL pointer dereference (e.g., when running ethtool -S). The root cause is that xdp_tx_queue_count starts at num_possible_cpus(...

CVE-2021-46916

A NULL pointer dereference flaw was found in ethtool loopback test in the Linux Kernel. This issue occurs due to a missing qvector associated with the test ring when it is setup, as interrupts are not normally added to the test rings. Exploiting the vulnerability can result in system crash and...
