Out-of-bounds Read in Linux Kernel AMDGPU SDMA IRQ Handling

IdentifiersCVE-2024-39471CWE-125· Out-of-bounds Read

CVE-2024-39471 is an out-of-bounds read vulnerability in the Linux kernel DRM AMDGPU driver. The SDMA v4.0 interrupt-ID-to-sequence conversion path did not stop processing when the mapping routine returned -EINVAL. Subsequent processing could use the failed result as an index, causing an out-of-bounds read. The upstream correction returns -EINVAL immediately when sequence mapping fails.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A successful trigger can cause an out-of-bounds memory read in kernel context. The available information does not establish reliable consequences beyond the invalid memory access; depending on the execution context and accessed memory, this may result in kernel instability or denial of service and could potentially disclose kernel memory.

Mitigation

If you can’t patch tonight, do this now.

No specific workaround is available. Until an updated kernel can be deployed, limit use of affected AMDGPU hardware and restrict untrusted users' ability to execute workloads that interact with the GPU driver where operationally feasible.

Remediation

Patch, then assume compromise.

Update to a kernel release containing the upstream fix: 5.4.278, 5.10.219, 5.15.161, 6.1.94, 6.6.34, 6.9.5, 6.10-rc1, or a vendor kernel package that backports the fix. For affected Red Hat Enterprise Linux systems, install the applicable vendor kernel erratum, including RHEL 8, RHEL 9, or RHEL 9.4 EUS updates, then reboot so the updated kernel is active.
