In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix undefined shift of user RQ WQE size set rq size computes the RQ WQE size as "1 rq wqe shift" based on the user-provided rq wqe shift, which is only checked to be greater than 32, so shifts of 32 are still accepted....

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...
