CVE-2026-89505

A flaw was found in the Linux kernel's RDMA/uverbs component. Malformed input from a provider in the legacy write path can cause the uverbsgethandlerfn function to dereference an uninitialized pointer. This can lead to a system crash, resulting in a denial of service...

CVE-2026-89506

A flaw was found in the Linux kernel's RDMA/uverbs component. A missing update to the UVERBSMETHODREGMR ioctl allows a malicious userspace program to trigger a null pointer dereference in specific RDMA drivers mthca, irdma, siw. This can lead to a system crash, resulting in a Denial of Service Do...

CVE-2026-89505

In the Linux kernel, the following vulnerability has been resolved: RDMA/uverbs: Guard legacy bundles without methodelm The legacy write path dispatches through a uverbsapiwritemethod, but the uverbsattrbundle passed to provider code does not have an ioctl method element. If malformed provider...

CVE-2026-89506

CVE-2026-89506 affects the Linux kernel RDMA/uverbs subsystem. The root cause is a missing UVERBS_ATTR_UHW attribute in the UVERBS_METHOD_REG_MR ioctl definition. Three drivers—mthca , irdma , and siw —associate UHW data with reg_mr but assume the udata pointer is non-NULL. Because the attribute ...

CVE-2026-89505

CVE-2026-89505 is a vulnerability in the Linux kernel RDMA/uverbs subsystem. In the legacy write() path, the uverbs_attr_bundle passed to provider code does not contain an ioctl method element. If malformed provider input causes the common uverbs validation code to emit an error message, uverbs_g...
