For a sequence-zero packet it then disables IBS,\nmarks memdump collection active, and reads the advertised dump size.\n\nIf the controller reports a zero dump size, the error path frees the\nlocal qca_memdump object and returns without clearing qca->qca_memdump\nor undoing the collection state. A later memdump work item initializes\nits local pointer from qca->qca_memdump and skips allocation when that\npointer is non-NULL, so it can operate on freed memory. The stale\ncollection and IBS-disabled flags can also leave waiters or later\ntransmit handling blocked behind an aborted dump.\n\nClear the saved pointer and memdump state before returning from the\ninvalid-size path, matching the cleanup used when hci_devcd_init() fails.\n\nA static analysis checker reported the stale memdump state, and manual\nsource review confirmed the invalid-size failure path."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/bluetooth/hci_qca.c"], "versions": [{"version": "06d3fdfcdf5cefb06f2024b9d3dad356779399cf", "lessThan": "5a3945e8dea6c9a8ec9e981169ac9487e1d6ad6a", "status": "affected", "versionType": "git"}, {"version": "06d3fdfcdf5cefb06f2024b9d3dad356779399cf", "lessThan": "069258d5111eed9ac9586bee42d03d38e2975715", "status": "affected", "versionType": "git"}, {"version": "06d3fdfcdf5cefb06f2024b9d3dad356779399cf", "lessThan": "cefb44c367b2b52e50f97bc8526d39df9bcf5e60", "status": "affected", "versionType": "git"}, {"version": "06d3fdfcdf5cefb06f2024b9d3dad356779399cf", "lessThan": "2363a757694752426fc47f3eadde15cf5f791fa5", "status": "affected", "versionType": "git"}, {"version": "06d3fdfcdf5cefb06f2024b9d3dad356779399cf", "lessThan": "bf587a10c33e5571a299742e45bc18960b9912e7", "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/bluetooth/hci_qca.c"], "versions": [{"version": "6.6", "status": "affected"}, {"version": "0", "lessThan": "6.6", "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-rc4", "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": "6.6", "versionEndExcluding": "6.6.148"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.12.101"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "6.18.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "7.1.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.6", "versionEndExcluding": "7.2-rc4"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/5a3945e8dea6c9a8ec9e981169ac9487e1d6ad6a"}, {"url": "https://git.kernel.org/stable/c/069258d5111eed9ac9586bee42d03d38e2975715"}, {"url": "https://git.kernel.org/stable/c/cefb44c367b2b52e50f97bc8526d39df9bcf5e60"}, {"url": "https://git.kernel.org/stable/c/2363a757694752426fc47f3eadde15cf5f791fa5"}, {"url": "https://git.kernel.org/stable/c/bf587a10c33e5571a299742e45bc18960b9912e7"}], "title": "Bluetooth: hci_qca: Clear memdump state on invalid dump size", "x_generator": {"engine": "bippy-1.2.0"}}}}
