CVE-2023-53628
Public on
Last Modified:
Description
A logic error was found in the Linux kernel amdgpu graphics driver's interrupt handling for GFX version 11 hardware. A local user with access to an AMD GPU can trigger a GPU device reset or suspend operation, causing the driver to attempt cleanup of a retired interrupt handler that no longer exists, which results in a kernel call trace and denial of service through system crash or GPU malfunction.
Statement
The issue arises because the gfx_v11_0_cp_ecc_error_irq interrupt handler was retired in GFX11 hardware, but the cleanup path in gfx_v11_0_hw_fini still attempts to disable this non-existent interrupt via amdgpu_irq_put. When GPU recovery or device suspend operations execute on affected hardware, the driver follows the standard teardown sequence and hits this stale reference, producing a call trace. Any workload that triggers GPU reset (such as through debugfs, recovery from GPU hang, or system suspend) will encounter this condition. The impact is limited to availability; there is no evidence of memory corruption or information disclosure, only disruption of GPU functionality.
Mitigation
To mitigate this issue, prevent the amdgpu module from loading. See https://access.redhat.com/solutions/41278 for instructions on blacklisting kernel modules.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authorities (CNA) source for its products and services (see Red Hat classifications ).
| CVSS v3 Score Breakdown | Red Hat | NVD |
|---|---|---|
| CVSS v3 Base Score | 5.5 | 5.5 |
| Attack Vector | Local | Local |
| Attack Complexity | Low | Low |
| Privileges Required | Low | Low |
| User Interaction | None | None |
| Scope | Unchanged | Unchanged |
| Confidentiality Impact | None | None |
| Integrity Impact | None | None |
| Availability Impact | High | High |

My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
- "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
- "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.
What can I do if my product is listed as "Will not fix"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
What can I do if my product is listed as "Fix deferred"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
- Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.
What is a mitigation?
I have a Red Hat product but it is not in the above list, is it affected?
Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?
My product is listed as "Out of Support Scope". What does this mean?
