Researcher releases Wake & Break exploit for AMD Navi31 GPU PSP
Researcher bl4sty announced Wake & Break, an exploit against the PSP (Platform Security Processor) of AMD Navi31 cards that allows manipulation of GPU firmware components. No AMD fix or advisory is mentioned in the sources, and no malicious exploitation has been reported. Navi31 users should track AMD advisories.
What happened
Researcher bl4sty published Wake & Break, an exploit for the PSP (Platform Security Processor) on AMD Navi31 cards. The tool allows tampering with firmware components running on the GPU. The sources mention no AMD advisory or fix.
Why it matters
The PSP guards card firmware; with the exploit public, anyone holding the card can alter components AMD considers off limits. The sources report no attacks, exposed data or downtime. The concern is firmware integrity where these GPUs support critical systems.
What to do
No patch is known. Track AMD advisories for Navi31 and inventory where these GPUs run. Assess risk where firmware trust chains are required.
For the technical team
- Affected
- GPUs AMD Navi31 (firmware do PSP, o Platform Security Processor) · AMD Navi31 GPUs (PSP firmware). Versions not specified in the source.
- Exploitation
- PoC publicly announced by @bl4sty on X on 2026-10-26. No malicious exploitation reported in the sources; no CVE or KEV mentioned.
- Fix
