Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix list_del corruption in kfd_criu_resume_svm The cleanup tail of kfd_criu_resume_svm() walks svms->criu_svm_metadata_list and kfree()s each struct criu_svm_metadata without removing it from the list. The list head is left pointing at freed kmalloc-96 objects. A second AMDKFD_IOC_CRIU_OP from the same process re-enters: list_empty() reads the dangling ->next (use-after-free), the loop walks freed entries, and each is kfree()'d again (double-free). This is reachable by an unprivileged render-group user via /dev/kfd with no capabilities required. Add list_del() before the kfree() so the list is properly emptied. The list_for_each_entry_safe() iterator already caches the next pointer, so unlinking during the walk is safe. (cherry picked from commit 6322d278a298e2c1430b9d2697743d3a04b788b1)
