CVE-2023-53723

Suspend warning via unconditional ECC IRQ disable

Published Oct 22, 2025 · Updated Oct 22, 2025

Improper IRQ handling in the Linux kernel allows attackers to produce a kernel warning by initiating an AMDGPU suspend cycle. The sdma_v4_0_hw_fini path calls amdgpu_irq_put to disable ecc_irq unconditionally, including on ASICs where SDMA RAS never enabled that interrupt. The condition requires SDMA IP 4.0 hardware without SDMA ECC; the published record establishes no consequence beyond the warning or specific attacker-access requirement.
