NVD Vulnerability Detail

CVE-2017-5577

Summary	The vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux kernel before 4.9.7 does not set an errno value upon certain overflow detections, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) via inconsistent size values in a VC4_SUBMIT_CL ioctl call.

Linux Kernel の VideoCore DRM ドライバの drivers/gpu/drm/vc4/vc4_gem.c におけるサービス運用妨害 (DoS) の脆弱性

Title	Linux Kernel の VideoCore DRM ドライバの drivers/gpu/drm/vc4/vc4_gem.c におけるサービス運用妨害 (DoS) の脆弱性
Summary	Linux Kernel の VideoCore DRM ドライバの drivers/gpu/drm/vc4/vc4_gem.c の vc4_get_bcl 関数は、特定のオーバーフローの検出に errno 値を設定しないため、サービス運用妨害 (不正なポインタデリファレンスおよび OOPS) 状態にされる脆弱性が存在します。
Possible impacts	ローカルユーザにより、VC4_SUBMIT_CL ioctl コールの整合性のないサイズ値を介して、サービス運用妨害 (不正なポインタデリファレンスおよび OOPS) 状態にされる可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。
