About this tag
The intel ice driver tag covers discussions about Intel's ice Ethernet driver for Linux, focusing on security vulnerabilities and kernel-level bugs. Recent threads address CVE-2026-23377, which involves an XDP fragment size mismatch in the ice driver that could cause correctness or memory-safety issues, and CVE-2024-42107, a TOCTOU race condition in the ice driver's PTP timestamp handling that could lead to kernel panics. These topics highlight the driver's role in high-performance networking and the importance of timely patches from upstream Linux and Microsoft's Security Update Guide.

    CVE-2026-23377: Fixing ice Driver XDP Frag Size from xdp.frame_sz

    CVE-2026-23377 is a Linux kernel networking issue in Intel’s ice driver, and the patch title itself gives away the core of the problem: the XDP receive queue’s fragment size was being derived from the DMA write length instead of the actual xdp.frame_sz. That sounds small, but in high-performance...

    CVE-2024-42107 TOCTOU in Intel ice Driver Fixed Upstream (Kernel Panic)

    The Linux kernel patch for CVE-2024-42107 fixes a race in the Intel "ice" network driver where an external timestamp interrupt handler could process a timestamp after the driver had released its Precision Time Protocol (PTP) clock — a timing-of-check/time-of-use (TOCTOU) race that could produce...
