CVE-2026-74299

A flaw was found in the Linux kernel's RDMA/core component. When aging pools with pinned handles, a failure to move handles from the active queue to an inactive queue during new page allocation can lead to a memory leak. This occurs because the system does not properly handle the fault, resulting...

CVE-2026-74298

A flaw was found in the RDMA/core component of the Linux kernel. This vulnerability occurs when the push to the pool fails, leading to a failure in the destruction of FRMR Fast Registration Memory Region handles. This can result in a resource leak, potentially impacting system stability or...

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...
