CVE-2023-54223 net/mlx5e: xsk: Fix invalid buffer access for legacy rq

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix invalid buffer access for legacy rq The below crash can be encountered when using xdpsock in rx mode for legacy rq: the buffer gets released in the XDPREDIRECT path, and then once again in the driver. This fix...

CVE-2023-54223

CVE-2023-54223: In the Linux kernel mlx5 net/xsk legacy-rq path, a buffer could be released twice (in XDP_REDIRECT and then by the driver) due to switching from a skip-release flag to fragment-counts. The fix adds a guard flag to avoid driver-side release, preventing a use-after-free/general-prot...
