Description
A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem, specifically within the `rxe` component. This vulnerability arises from an incorrect conversion of I/O Virtual Addresses (iova) to Virtual Addresses (va) when Memory Regions (MRs) have page sizes that differ from the system's `PAGE_SIZE`. An attacker could potentially exploit this flaw to cause incorrect memory access, which may lead to system instability or a kernel panic, resulting in a Denial of Service (DoS).
