CVE-2026-68293

A flaw was found in the net/mlx5 driver of the Linux kernel. When the driver attempts to read the MCIA register from a device advertising the mcia32dwords capability, the mlx5querymcia function can read more data than the allocated buffer can hold. This leads to a buffer overflow, which can cause...
