Kernel memory corruption via cxgb4 length overflow
Published Feb 27, 2025 · Updated Sep 8, 2026
Integer overflow in the Linux cxgb4 driver allows remote attackers to corrupt kernel memory via TCP SYN traffic to an iWARP listener. copy_gl_to_skb_pkt sizes an skb with an unchecked 32-bit addition of gl->tot_len and header lengths before copying received data. Exposure requires a 32-bit kernel with a Chelsio T4 or T5 RDMA adapter, and the upstream analysis states that hardware length masking prevents a peer from reaching the wrapping value.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
