The child\nplatform devices already registered by mfd_add_devices() remain\nregistered and are never released.\n\nRemove the children from the power domain and unregister the MFD\ndevices on failures that occur after mfd_add_devices() succeeds. Keep\nmfd_add_devices() failures on the existing cleanup path since the MFD\ncore already rolls back partially registered children itself.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review.\n\n(cherry picked from commit 63da68d6a2279ec945581c990c5a59a5ae8b5560)"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c"],"versions":[{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"385ad314f1c096aae71fff516214bb312a6047fb","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"7b7f770f48be77ce38e93216983dcdf1ea3a42ba","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"65ef6645982ccde16a7bc98d025eb80f5fab47f6","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"d700c26ed64bd3c26e4aa7679b9d5f3333c3747a","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"2b9a53940a2bc063ea4cd09ee49220a503a0170c","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"587469076e4ffb617f7ad1a0c4a13072a3e87113","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"abf854513bc19e6e24d45353ac99ec5627ee0acc","status":"affected","versionType":"git"},{"version":"25030321ba2860c56651429a4f28d94a6483d952","lessThan":"f0013046151b7467e62c471c1c83d63ea255799c","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/amd/amdgpu/amdgpu_acp.c"],"versions":[{"version":"4.6","status":"affected"},{"version":"0","lessThan":"4.6","status":"unaffected","versionType":"semver"},{"version":"5.10.273","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.224","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.191","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","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":"4.6","versionEndExcluding":"5.10.273"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"5.15.224"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"6.1.191"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"6.6.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"6.12.113"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"6.18.56"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"7.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.6","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/385ad314f1c096aae71fff516214bb312a6047fb"},{"url":"https://git.kernel.org/stable/c/7b7f770f48be77ce38e93216983dcdf1ea3a42ba"},{"url":"https://git.kernel.org/stable/c/65ef6645982ccde16a7bc98d025eb80f5fab47f6"},{"url":"https://git.kernel.org/stable/c/d700c26ed64bd3c26e4aa7679b9d5f3333c3747a"},{"url":"https://git.kernel.org/stable/c/2b9a53940a2bc063ea4cd09ee49220a503a0170c"},{"url":"https://git.kernel.org/stable/c/587469076e4ffb617f7ad1a0c4a13072a3e87113"},{"url":"https://git.kernel.org/stable/c/abf854513bc19e6e24d45353ac99ec5627ee0acc"},{"url":"https://git.kernel.org/stable/c/f0013046151b7467e62c471c1c83d63ea255799c"}],"title":"drm/amdgpu: fix ACP MFD device leak on init failure","x_generator":{"engine":"bippy-1.2.0"}}}}
