CVE-2021-46931

CVE-2021-46931 involves the Linux kernel mlx5e path (net/mlx5e, mlx5_core) where a TX-timeout-recovery flow calls mlx5e_tx_reporter_dump_sq() with a void* that is actually a mlx5e_tx_timeout_ctx*. The mismatch corrupts stack state and can trigger a kernel panic/stack overflow. The fix adds a wrap...
