How to fix?

There is no fixed version for RHEL:8 openshift/ose-rhel-coreos-9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift/ose-rhel-coreos-9 package and not the openshift/ose-rhel-coreos-9 package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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)
