CVE-2023-53723
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: disable sdma ecc irq only when sdma RAS is enabled in suspend
sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini, driver unconditionally disables ecc_irq which is only enabled on those asics enabling sdma ecc. This will introduce a warning in suspend cycle on those chips with sdma ip v4.0, while without sdma ecc. So this patch correct this.

AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
In the Linux kernel, a fix prevents a warning during suspend on AMD GPUs with SDMA IP v4.0 that lack SDMA ECC support.
Vulnerability
In the Linux kernel's AMDGPU driver, the sdma_v4_0_hw_fini function is shared across multiple ASICs. During the suspend cycle, the driver unconditionally disables the SDMA ECC interrupt (ecc_irq) in sdma_v4_0_hw_fini. However, this interrupt is only enabled on ASICs that support SDMA ECC (RAS). On chips with SDMA IP v4.0 that do not have SDMA ECC, this unconditional disable triggers a warning and a call trace, as shown in the kernel log [1].
Exploitation
This issue is triggered during the system suspend process. An attacker would need local access to the system and the ability to trigger a suspend cycle (e.g., via systemctl suspend or closing a laptop lid). No special privileges beyond normal user access to suspend the system are required. The vulnerability manifests as a kernel warning, not a memory corruption or privilege escalation.
Impact
The primary impact is a kernel warning and a call trace printed to the kernel log during suspend. This can cause unnecessary noise in logs and potentially disrupt automated monitoring or suspend/resume workflows. There is no evidence of data corruption, privilege escalation, or denial of service beyond the warning itself.
Mitigation
The fix, introduced in Linux kernel commits [1] and [2], modifies sdma_v4_0_hw_fini to only disable the SDMA ECC interrupt when SDMA RAS is actually enabled. Users should update to a kernel version containing this patch. No workaround is available other than avoiding suspend on affected systems.
