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 813443721331 ("drm/nouveau/disp: move DP link config into acquire") Coverity reported the following: *** CID 1527268: Memory - corruptions (OVERRUN) drivers/gpu/drm/nouveau/dispnv50/disp.c:1817 in nv50_pior_atomic_enable() 1811 case DCB_OUTPUT_TMDS: 1812 ctrl |= NVDEF(NV507D, PIOR_SET_CONTROL, PROTOCOL, EXT_TMDS_ENC); 1813 nvif_outp_acquire_tmds(&nv_encoder->outp, false, false, 0, 0, 0, false); 1814 break; 1815 case DCB_OUTPUT_DP: 1816 ctrl |= NVDEF(NV507D, PIOR_SET_CONTROL, PROTOCOL, EXT_TMDS_ENC); vvv CID 1527268: Memory - corruptions (OVERRUN) vvv Overrunning array "(*nv_encoder).dp.dpcd" of 15 bytes by passing it to a function which accesses it at byte offset 15. 1817 nvif_outp_acquire_dp(&nv_encoder->outp, nv_encoder->dp.dpcd, 0, 0, false, false); 1818 break; 1819 default: 1820 BUG(); 1821 break; 1822 } 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: 1527268 ("Memory - corruptions") Fixes: 813443721331 ("drm/nouveau/disp: move DP link config into acquire") Thanks for your attention! -- Coverity-bot
