fore200e

About this tag
The fore200e tag on WindowsForum.com covers the Linux FORE200E ATM driver, specifically a recently recorded kernel vulnerability (CVE-2025-68339) involving a synchronization bug in the fore200e_open function. This bug can corrupt bandwidth accounting when error paths run concurrently with normal operations. The upstream fix involves holding the device's rate mutex (rate_mtx) in the error path when restoring a reserved available_cell_rate. Administrators and embedded vendors should validate and apply the patch or updated kernel packages to address this issue.

  1. CVE-2025-68339: Linux FORE200E Open Path Race Fix with Rate Mutex

    A recently recorded Linux-kernel vulnerability affects the FORE200E ATM driver: a small but meaningful synchronization bug in fore200e_open that can corrupt the driver’s bandwidth accounting when error paths run concurrently with normal control operations. The upstream fix is straightforward —...
