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...

CVE-2026-72345

A flaw was found in the Linux kernel's mlx5 LAG Link Aggregation Group driver. An off-by-one error in the mlx5lagcreatesinglefdb function's error rollback mechanism can lead to operations on uninitialized memory or a double-free condition. This could result in system instability or a denial of...

CVE-2026-72341

A flaw was found in the Linux kernel's net/mlx5e component. A local attacker could exploit a race condition during the publication of channel statistics. On weakly-ordered architectures, this could lead to a null pointer dereference, causing a system crash and a denial of service...

CVE-2026-72032

A flaw was found in the Linux kernel's net/mlx5 HWS Hardware Steering component. This vulnerability occurs when the hwsbwcmatchermove function attempts to resize a matcher, and the mlx5hwsmatcherresizesettarget operation fails. In such a scenario, a replacement matcher is allocated but not proper...
