The result\nis fed straight into amdgpu_vm_bo_va_for_each_valid_mapping(), which\nexpands to list_for_each_entry(mapping, &(bo_va)->valids, list) and\ndereferences bo_va, causing a NULL pointer dereference.\n\nThis is reachable by any process able to issue the ioctl (render group)\nsimply by requesting mapping info for an unmapped BO.\n\nReturn -ENOENT when no bo_va is found, jumping to out_exec so the\ndrm_exec context and GEM object reference are released.\n\n(cherry picked from commit 528b19377affc1cc7362a70a254c1dda793595f9)"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c"],"versions":[{"version":"4d82724f7f2b847eb0454b1aab5450545b39abd4","lessThan":"ddba17b3dfa0efc80d6c98621c2fb7af66adb622","status":"affected","versionType":"git"},{"version":"4d82724f7f2b847eb0454b1aab5450545b39abd4","lessThan":"9faf4c66edb6bcb8ca0465c3a4868bb7f278cd31","status":"affected","versionType":"git"},{"version":"4d82724f7f2b847eb0454b1aab5450545b39abd4","lessThan":"93475c34111916df71c63e510fc52db01351f809","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.42","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.6","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ddba17b3dfa0efc80d6c98621c2fb7af66adb622"},{"url":"https://git.kernel.org/stable/c/9faf4c66edb6bcb8ca0465c3a4868bb7f278cd31"},{"url":"https://git.kernel.org/stable/c/93475c34111916df71c63e510fc52db01351f809"}],"title":"drm/amdgpu: check amdgpu_vm_bo_find() result in GET_MAPPING_INFO","x_generator":{"engine":"bippy-1.2.0"}}}}
