CVE-2026-68143 addresses a race condition in the Linux SLIP serial-networking driver that could lead to an out-of-bounds write or use-after-free during an MTU change. For Windows users, this is not a Windows TCP/IP or Patch Tuesday issue; exposure is limited to Linux kernels with the SLIP driver enabled, including custom or device-connected WSL 2 deployments. The NVD record, sourced from kernel.org, identifies the fault in drivers/net/slip/slip.c. The upstream patch, authored by Sungmin Kang, entered the networking tree in late July, with the Linux 7.2-rc5 change list documenting the fix.
