This\nworks fine for DPU code (where most of the regions are aligned), but\nfails for snapshotting of the DSI data (because DSI data region is\nshifted by 4 bytes). Fix the code by removing length alignment and by\naccurately printing last registers in the region. While reworking the\ncode also fix the 16x memory overallocation in\nmsm_disp_state_dump_regs().\n\nPatchwork: https://patchwork.freedesktop.org/patch/725449/"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","baseScore":7.7,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c"],"versions":[{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"8fb070cf95847b29ef6cb15ec2c0de2bf4704676","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"cecd34e046121d788a70b5c8b4f8a88916637953","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"070e40acc59ef7bedba0314f59971ba87fcc8ab0","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"1ef79be774706dddcfcace0331fa7ff32a73c73e","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"cdd1aaf0ee962f50810b9aef7928f2313989d55f","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"0c90ececfad3fc5c4c43a75ece0e2d736ab3def1","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"76824d2467feb1828b745d6add2541918d7be3da","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/msm/disp/msm_disp_snapshot_util.c"],"versions":[{"version":"5.14","status":"affected"},{"version":"0","lessThan":"5.14","status":"unaffected","versionType":"semver"},{"version":"5.15.209","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.175","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.142","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.92","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.34","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.11","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"5.14","versionEndExcluding":"5.15.209"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.1.175"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.6.142"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.12.92"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.18.34"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"7.0.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8fb070cf95847b29ef6cb15ec2c0de2bf4704676"},{"url":"https://git.kernel.org/stable/c/cecd34e046121d788a70b5c8b4f8a88916637953"},{"url":"https://git.kernel.org/stable/c/070e40acc59ef7bedba0314f59971ba87fcc8ab0"},{"url":"https://git.kernel.org/stable/c/1ef79be774706dddcfcace0331fa7ff32a73c73e"},{"url":"https://git.kernel.org/stable/c/cdd1aaf0ee962f50810b9aef7928f2313989d55f"},{"url":"https://git.kernel.org/stable/c/0c90ececfad3fc5c4c43a75ece0e2d736ab3def1"},{"url":"https://git.kernel.org/stable/c/76824d2467feb1828b745d6add2541918d7be3da"}],"title":"drm/msm/snapshot: fix dumping of the unaligned regions","x_generator":{"engine":"bippy-1.2.0"}}}}
