No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.5.0-rc1+ #31
Description
The Linux kernel contains an issue in the net/mlx5e module related to xsk (XDP socket) handling of buffers for legacy request queues (rq). A crash can occur when using xdpsock in receive (rx) mode for legacy rq, where a buffer is released twice – once in the XDP REDIRECT path and again in the driver. The fix avoids releasing the buffer on the driver side. This issue arises from a change in how fragment counts for pages are handled, replacing the skip release flag. The crash log indicates a general protection fault related to an invalid memory address.
Recommendations
Update to a version newer than 6.5.0-rc1+ #31.
