In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: free the userptr ranges when a CS fails after parser_bos

amdgpu_cs_parser_bos() allocates an HMM range for every userptr entry of the BO list and looks up the user pages. Those ranges are only freed when amdgpu_cs_parser_bos() itself fails or when amdgpu_cs_submit() checks them under the notifier lock. If amdgpu_cs_patch_jobs(), amdgpu_cs_vm_handling(), amdgpu_cs_sync_rings() or the early part of amdgpu_cs_submit() fails, nothing frees them: neither amdgpu_cs_parser_fini() nor amdgpu_bo_list_free() touch e->range.

Each such CS then leaks the range, its hmm_pfns array (8 bytes per page of the userptr BO) and the BO reference the range holds. An IB on a ring that patches the CS in place (e.g. VCN) with an unmapped va_start fails in amdgpu_cs_patch_ibs() and takes this path.

Free the ranges on those error paths. Ranges amdgpu_cs_submit() already dropped are NULL, so freeing them again is a no-op.

(cherry picked from commit c52a9542ed7cfd527feb938bd0accada2ac8d267)

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
