| Vector | AV:L/AC:L/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
The issue is related to incorrect descriptor free behavior in the ENA component of the Linux kernel. It involves two types of TX queues: one for packets arriving from the network stack and another for packets forwarded by XDP REDIRECT or XDP TX instructions. The
ena free tx bufs() function incorrectly assumes that the processed TX queue is from the first category, leading to incorrect use of napi consume skb() for descriptors in XDP-specific queues. This results in descriptors not being freed correctly during a VF reset, causing crashes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
