CVE-2026-46114

A flaw was found in the Linux kernel's RDMA (Remote Direct Memory Access) subsystem, specifically within the rxe driver. A remote attacker could exploit this vulnerability by sending a specially crafted ATOMIC_WRITE request with a zero-byte payload. This improper handling of non-8-byte ATOMIC_WRITE payloads allows the attacker to read past the intended packet boundary. Consequently, sensitive kernel memory, such as kernel strings and partial kernel-direct-map pointer words, can be disclosed into the attacker's memory region.
