"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-099903 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx ras

    gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert.
    So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq
    should be executed under such condition, otherwise, an amdgpu_irq_put
    calltrace will occur.
