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\nmsi2500_start_streaming() had five error paths that all hit this trap\nand were further tangled by ret-overwriting between calls:\n\n - -ENODEV when the USB device was already disconnected\n - -ERESTARTSYS when mutex_lock_interruptible() was interrupted\n - msi2500_set_usb_adc() failure: ret was silently overwritten by\n the next call (msi2500_isoc_init), so the error was lost entirely\n - msi2500_isoc_init() failure: cleanup_queued_bufs was called, but\n the function then fell through to msi2500_ctrl_msg() and again\n masked the original error by overwriting ret\n - msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,\n leaving isoc URBs submitted with no way for the driver to consume\n them\n\nConsolidate the error paths into a small goto chain. Every failure\nnow stops the function, drains the queued-buffer list, and returns\nthe real error code. The ctrl_msg failure path also rolls back the\npreceding msi2500_isoc_init() via msi2500_isoc_cleanup() before\nunlocking and draining.\n\nThe cleanup helper takes a vb2_buffer_state argument so that the\nstart_streaming error paths can pass VB2_BUF_STATE_QUEUED (as\nexpected by userspace on start_streaming failure) while stop_streaming\nkeeps its existing VB2_BUF_STATE_ERROR semantics.\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/usb/msi2500/msi2500.c"], "versions": [{"version": "977e444f59ad16eedf66acae4f357011c74da291", "lessThan": "1d58229b330b7f67fbfa07e0f2a8a51fbeafaa9a", "status": "affected", "versionType": "git"}, {"version": "977e444f59ad16eedf66acae4f357011c74da291", "lessThan": "bab9d5a67d4db96ae8c187b92b37979911302a10", "status": "affected", "versionType": "git"}, {"version": "977e444f59ad16eedf66acae4f357011c74da291", "lessThan": "264b5380c4f8aa92dbc2983ecd2b627f1d5e0061", "status": "affected", "versionType": "git"}, {"version": "977e444f59ad16eedf66acae4f357011c74da291", "lessThan": "3673cb0a5711e910074d69201da9e1535c03f97a", "status": "affected", "versionType": "git"}, {"version": "977e444f59ad16eedf66acae4f357011c74da291", "lessThan": "7201c17786a498497bca57752883b90914d405ac", "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/usb/msi2500/msi2500.c"], "versions": [{"version": "3.12", "status": "affected"}, {"version": "0", "lessThan": "3.12", "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": "3.12", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.12", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.12", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.12", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.12", "versionEndExcluding": "7.2-rc1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/1d58229b330b7f67fbfa07e0f2a8a51fbeafaa9a"}, {"url": "https://git.kernel.org/stable/c/bab9d5a67d4db96ae8c187b92b37979911302a10"}, {"url": "https://git.kernel.org/stable/c/264b5380c4f8aa92dbc2983ecd2b627f1d5e0061"}, {"url": "https://git.kernel.org/stable/c/3673cb0a5711e910074d69201da9e1535c03f97a"}, {"url": "https://git.kernel.org/stable/c/7201c17786a498497bca57752883b90914d405ac"}], "title": "media: msi2500: Return queued buffers on start_streaming() failure", "x_generator": {"engine": "bippy-1.2.0"}}}}
