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/"}], "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"}}}}
