CVE-2026-74297

A flaw was found in the Linux kernel's RDMA/mlx5 subsystem. Insufficient validation of a user-provided input, rqwqeshift, in the setrqsize function can lead to an integer overflow. This overflow results in an undefined shift operation, which may cause system instability or a denial of service...

CVE-2026-74296

A flaw was found in the RDMA/mlx5 component of the Linux kernel. This vulnerability occurs due to an incorrect User Access Register UAR index release, where the software-provided index is freed instead of the hardware-provided one. This improper resource management could potentially lead to...
