CVE-2026-93103

A flaw was found in the Linux kernel's RDMA/hfi1 component. During an allocation failure, the hfi1freedevdata function can incorrectly attempt to free a device that was not properly initialized. This can lead to the removal of an unrelated device from the system's unit table. The consequence of...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/hfi1: Preserves unit 0 in case of allocation failure. The hfi1freedevdata function assumes that the device was added to the unit table and erases dd-unit unconditionally. If xaallocirq fails, the zero-initialized unit...

CVE-2026-93103

CVE-2026-93103 affects the Linux kernel in the RDMA/hfi1 driver. The root cause is that hfi1_free_devdata() unconditionally erases dd->unit from the unit table, assuming the device was successfully inserted. If xa_alloc_irq() fails, the zero-initialized unit remains at index 0, meaning cleanup...
