10.1.11 or 10.2.x prior to 10.2.6 or 11.0.x prior to 11.0.3. It is, therefore, affected by a vulnerability.

  - BGP software such as FRRouting FRR included as part of the PAN-OS, Prisma SD-WAN ION, and Prisma Access
    routing features enable a remote attacker to incorrectly reset network sessions though an invalid BGP
    update. This issue is applicable only to devices and appliances with BGP routing features enabled.
