CVE-2026-46133

A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...

CVE-2026-46133

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Reject unknown opcodes before ICRC processing Even after applying commit 7244491dab34 "RDMA/rxe: Validate pad and ICRC before payloadsize in rxercv", a single unauthenticated UDP packet can still trigger panic. That pat...

CVE-2026-46133

The CVE-2026-46133 issue affects Linux kernel’s Soft RoCE (RDMA/rxe) where an unauthenticated UDP packet with an unknown opcode could trigger an out-of-bounds read during ICRC/CRC processing due to missing validation of opcodes before length arithmetic. The advisory describes that entries in the ...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from insufficient ICRC checks when processing unknown opcodes in RDMA rxe, potentially leading to out-of-bou...
