Depending on kernel version, architecture, and config (`sizeof(struct hci_dev)` relative to the kmalloc bucket, particularly on the 32-bit ARM boards that use this exact driver), those bytes land in the head of the adjacent heap object, giving a repeatable heap-overflow primitive that can be groomed by controlling what occupies the neighbouring slot.\nA:H - Corrupting the first bytes of a neighbouring kmalloc object, and later dereferencing pointers read back out of bounds in `btrtl_dmp_hdr()`, readily produces a kernel oops or panic; the access is repeated on every probe, resume, and device open. On builds with KASAN or arm64 MTE (shipped in production on some Android devices), the very first occurrence is a fatal report/panic, and `panic_on_warn`/`panic_on_oops` hardened embedded and automotive builds turn it into an immediate full system outage."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "5b355944b19011011dd3fd4187444c5ff1d76ad2", "lessThan": "dd163fa34c483f1674aa2510accce11a224f649e", "versionType": "git"}, {"status": "affected", "version": "5b355944b19011011dd3fd4187444c5ff1d76ad2", "lessThan": "2f232bc389a4f5943c40733582f9edf77b89e499", "versionType": "git"}, {"status": "affected", "version": "5b355944b19011011dd3fd4187444c5ff1d76ad2", "lessThan": "0c657e641df1e77d6087688190f632cad9c0439b", "versionType": "git"}, {"status": "affected", "version": "5b355944b19011011dd3fd4187444c5ff1d76ad2", "lessThan": "de4e88ec58c4202efd1f02eebb4939bbf6945358", "versionType": "git"}], "programFiles": ["drivers/bluetooth/hci_h5.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "6.2"}, {"status": "unaffected", "version": "0", "lessThan": "6.2", "versionType": "semver"}, {"status": "unaffected", "version": "6.6.23", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.7.11", "versionType": "semver", "lessThanOrEqual": "6.7.*"}, {"status": "unaffected", "version": "6.8.2", "versionType": "semver", "lessThanOrEqual": "6.8.*"}, {"status": "unaffected", "version": "6.9", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/bluetooth/hci_h5.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/dd163fa34c483f1674aa2510accce11a224f649e"}, {"url": "https://git.kernel.org/stable/c/2f232bc389a4f5943c40733582f9edf77b89e499"}, {"url": "https://git.kernel.org/stable/c/0c657e641df1e77d6087688190f632cad9c0439b"}, {"url": "https://git.kernel.org/stable/c/de4e88ec58c4202efd1f02eebb4939bbf6945358"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btrtl: fix out of bounds memory access\n\nThe problem is detected by KASAN.\nbtrtl driver uses private hci data to store 'struct btrealtek_data'.\nIf btrtl driver is used with btusb, then memory for private hci data\nis allocated in btusb.
