Description
In the Linux kernel, the following vulnerability has been resolved: amdgpu: validate offset_in_bo of drm_amdgpu_gem_va This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows. v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl

Executive Summary

This vulnerability in the Linux kernel's amdgpu driver involves an out-of-bounds (OOB) access issue caused by improper validation of the offset_in_bo parameter in the drm_amdgpu_gem_va function. Specifically, when offset_in_bo plus map_size overflows, it can lead to accessing memory outside the intended buffer. The fix involved adding proper validations in the amdgpu_vm_bo_map and amdgpu_vm_bo_replace_map functions to prevent this overflow and OOB access.

Impact Analysis

This vulnerability can lead to out-of-bounds memory access in the amdgpu driver, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges by exploiting the memory corruption.
