Hello! This is an experimental semi-automated report about issues detected by Coverity from a scan of next-20221110 as part of the linux-next scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by commits: Wed Nov 9 08:22:02 2022 +1000 f530bc60a30b ("drm/nouveau/disp: move HDMI config into acquire + infoframe methods") Coverity reported the following: *** CID 1527272: (OVERRUN) drivers/gpu/drm/nouveau/dispnv50/disp.c:801 in nv50_hdmi_enable() 795 796 size = hdmi_infoframe_pack(&infoframe, args.data, 17); 797 } else { 798 size = 0; 799 } 800 vvv CID 1527272: (OVERRUN) vvv Overrunning struct type nvif_outp_infoframe_v0 of 8 bytes by passing it to a function which accesses it at byte offset 21 using argument "size" (which evaluates to 14). 801 nvif_outp_infoframe(&nv_encoder->outp, NVIF_OUTP_INFOFRAME_V0_AVI, &args.infoframe, size); 802 803 /* Vendor InfoFrame. */ 804 if (!drm_hdmi_vendor_infoframe_from_display_mode(&infoframe.vendor.hdmi, 805 &nv_connector->base, mode)) 806 size = hdmi_infoframe_pack(&infoframe, args.data, 17); drivers/gpu/drm/nouveau/dispnv50/disp.c:810 in nv50_hdmi_enable() 804 if (!drm_hdmi_vendor_infoframe_from_display_mode(&infoframe.vendor.hdmi, 805 &nv_connector->base, mode)) 806 size = hdmi_infoframe_pack(&infoframe, args.data, 17); 807 else 808 size = 0; 809 vvv CID 1527272: (OVERRUN) vvv Overrunning struct type nvif_outp_infoframe_v0 of 8 bytes by passing it to a function which accesses it at byte offset 21 using argument "size" (which evaluates to 14). 810 nvif_outp_infoframe(&nv_encoder->outp, NVIF_OUTP_INFOFRAME_V0_VSI, &args.infoframe, size); 811 812 nv50_audio_enable(encoder, nv_crtc, nv_connector, state, mode); 813 } 814 815 /****************************************************************************** If this is a false positive, please let us know so we can mark it as such, or teach the Coverity rules to be smarter. If not, please make sure fixes get into linux-next. :) For patches fixing this, please include these lines (but double-check the "Fixes" first): Reported-by: coverity-bot <keescook+coverity-bot@xxxxxxxxxxxx> Addresses-Coverity-ID: 1527272 ("OVERRUN") Fixes: f530bc60a30b ("drm/nouveau/disp: move HDMI config into acquire + infoframe methods") It looks like this should address &args not &args.infoframe, if the intention is to include the "data" member. Thanks for your attention! -- Coverity-bot
