If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nsun4i_csi_start_streaming() returned -EINVAL when no matching CSI\nformat could be found, before any setup (scratch buffer allocation,\npipeline start) had been performed. The remaining error paths already\nconverge on the err_clear_dma_queue label, which calls\nreturn_all_buffers(..., VB2_BUF_STATE_QUEUED) under csi->qlock. Jump\nto that label directly: the intermediate err_disable_device /\nerr_disable_pipeline / err_free_scratch_buffer labels are skipped,\nwhich is correct because nothing they would undo has happened yet.\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\")."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/media/platform/sunxi/sun4i-csi/sun4i_dma.c"], "versions": [{"version": "577bbf23b758848f0c4a50d346460b690c753024", "lessThan": "4872161e6fbe4e1783daea8bff79caddfae0fb82", "status": "affected", "versionType": "git"}, {"version": "577bbf23b758848f0c4a50d346460b690c753024", "lessThan": "a8abecc638a7feb20b78fabd563b05e30c071331", "status": "affected", "versionType": "git"}, {"version": "577bbf23b758848f0c4a50d346460b690c753024", "lessThan": "b5184b3f0e9d4cc47059ba1138c9a73d43d2493f", "status": "affected", "versionType": "git"}, {"version": "577bbf23b758848f0c4a50d346460b690c753024", "lessThan": "668face37fdb6b6900645dc8777195498541c9a7", "status": "affected", "versionType": "git"}, {"version": "577bbf23b758848f0c4a50d346460b690c753024", "lessThan": "bbba3e260a62810a717b4442a3bb96d0ec0f6309", "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/media/platform/sunxi/sun4i-csi/sun4i_dma.c"], "versions": [{"version": "5.4", "status": "affected"}, {"version": "0", "lessThan": "5.4", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.148", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.101", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.42", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.6", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc1", "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": "5.4", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.4", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.4", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.4", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.4", "versionEndExcluding": "7.2-rc1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/4872161e6fbe4e1783daea8bff79caddfae0fb82"}, {"url": "https://git.kernel.org/stable/c/a8abecc638a7feb20b78fabd563b05e30c071331"}, {"url": "https://git.kernel.org/stable/c/b5184b3f0e9d4cc47059ba1138c9a73d43d2493f"}, {"url": "https://git.kernel.org/stable/c/668face37fdb6b6900645dc8777195498541c9a7"}, {"url": "https://git.kernel.org/stable/c/bbba3e260a62810a717b4442a3bb96d0ec0f6309"}], "title": "media: sun4i-csi: Return queued buffers on start_streaming() failure", "x_generator": {"engine": "bippy-1.2.0"}}}}
