Code execution via preconditioned heap out-of-bounds write
Published Jul 4, 2022 · Updated Aug 3, 2024
Out-of-bounds write in IpSecDxe in NVIDIA DGX A100 firmware before 22.5.5 allows local users to execute code through a crafted heap state. The SBIOS IpSecDxe module performs an out-of-bounds write when operating on a preconditioned heap. Elevated privileges and control over heap preconditioning are required; successful exploitation can execute code, disclose information, corrupt data, or interrupt service.
