Variable sized arrays have fallen out of fashion. There are various patches like that which fix this issue every time it crops up.
If you can still reproduce on the latest 6.9-rc kernels you should report a bug upstream to get the remaining cases fixed. Or if you feel comfortable you can write a patch for any remaining cases you hit. As you can see it's a trivial fix. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2039926 Title: Error UBSAN: array-index-out-of-bounds amdgpu (drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/smu7_hwmgr.c) Status in Linux: Fix Released Status in linux package in Ubuntu: Confirmed Status in linux-hwe-6.5 package in Ubuntu: Confirmed Bug description: Error in boot: [ 8.597520] UBSAN: array-index-out-of-bounds in /build/linux-D15vQj/linux-6.5.0/drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/smu7_hwmgr.c:3676:4 [ 8.597527] index 7 is out of range for type 'ATOM_Polaris_SCLK_Dependency_Record [1]' ProblemType: Bug DistroRelease: Ubuntu 23.10 Package: linux-image-generic 6.5.0.9.11 ProcVersionSignature: Ubuntu 6.5.0-9.9-generic 6.5.3 Uname: Linux 6.5.0-9-generic x86_64 ApportVersion: 2.27.0-0ubuntu5 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Fri Oct 20 09:28:16 2023 InstallationDate: Installed on 2022-10-12 (373 days ago) InstallationMedia: Ubuntu 22.04.1 LTS "Jammy Jellyfish" - Release amd64 (20220809.1) MachineType: {report['dmi.sys.vendor']} {report['dmi.product.name']} ProcFB: 0 amdgpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.5.0-9-generic root=UUID=9edc5478-c6c2-4cf3-9de8-01ccb697fb9e ro quiet splash audit=0 mitigations=off amdgpu.ppfeaturemask=0xffffffff vt.global_cursor_default=0 loglevel=2 rd.systemd.show_status=false rd.udev.log-prority=3 sysrq_always_enabled=1 audit=0 vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-6.5.0-9-generic N/A linux-backports-modules-6.5.0-9-generic N/A linux-firmware 20230919.git3672ccab-0ubuntu2.1 SourcePackage: linux UpgradeStatus: Upgraded to mantic on 2023-10-13 (6 days ago) dmi.bios.date: 07/11/2014 dmi.bios.release: 4.6 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: D3EMW08.110 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: D3F3-EM dmi.board.vendor: MEDION dmi.board.version: 1.0 dmi.chassis.type: 3 dmi.chassis.vendor: MEDION dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrD3EMW08.110:bd07/11/2014:br4.6:svnMEDION:pnD3F3-EM:pvr1.0:rvnMEDION:rnD3F3-EM:rvr1.0:cvnMEDION:ct3:cvr:skuTobefilledbyO.E.M.: dmi.product.family: To be filled by O.E.M. dmi.product.name: D3F3-EM dmi.product.sku: To be filled by O.E.M. dmi.product.version: 1.0 dmi.sys.vendor: MEDION To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2039926/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
