The OOB write side itself occurs in automatic discovery work that needs no privilege at all, so low privileges are the ceiling of what an attacker needs.\nUI:N - Device discovery, hotplug handling and controller reset run autonomously in the driver's firmware-event workqueue, and the ioctl path is a plain syscall. No victim action of any kind is required.\nS:U - The out-of-bounds access corrupts kernel slab memory from within kernel context; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:L - `test_bit()` reads an 8-byte word that extends past the allocation, but the overread is strictly bounded to at most 7 adjacent bytes and only the in-bounds bit is consumed, so no meaningful memory contents are returned to the attacker.\nI:H - This is an out-of-bounds write \u2014 KASAN reports `Write of size 8` past the slab allocation from `_scsih_add_device` \u2014 and the atomic RMW spans neighbouring heap bytes, which can clobber a concurrent non-atomic update to adjacent slab memory. Per the out-of-bounds-write classification this is scored High.\nA:H - The trailing word access crosses the object boundary, which faults into the guard page under KFENCE (enabled by default in mainstream distro and Android kernels) and raises a slab-out-of-bounds BUG under KASAN or SLUB redzoning, producing an oops or, with `panic_on_warn`, a full kernel panic."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "e9bce7c751f6d6c7be88c0bc081a66aaf61a23ee", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "19649e49a6df07cd2e03e0a11396fd3a99485ec2", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "0081d2b3ae0a17a86b8cc0fa3c8bdc54e233ba16", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "521f333e644c4246ca04a4fc4772edc53dd2a801", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "46bab2bcd771e725ff5ca3a68ba68cfeac45676c", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "9079338c5a0d1f1fee34fb1c9e99b754efe414c5", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "18abb5db0aa9b2d48f7037a88b41af2eef821674", "versionType": "git"}, {"status": "affected", "version": "c696f7b83edeac804e898952058089143f49ca0a", "lessThan": "4254dfeda82f20844299dca6c38cbffcfd499f41", "versionType": "git"}], "programFiles": ["drivers/scsi/mpt3sas/mpt3sas_base.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "4.10"}, {"status": "unaffected", "version": "0", "lessThan": "4.10", "versionType": "semver"}, {"status": "unaffected", "version": "4.19.317", "versionType": "semver", "lessThanOrEqual": "4.19.*"}, {"status": "unaffected", "version": "5.4.279", "versionType": "semver", "lessThanOrEqual": "5.4.*"}, {"status": "unaffected", "version": "5.10.221", "versionType": "semver", "lessThanOrEqual": "5.10.*"}, {"status": "unaffected", "version": "5.15.162", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.95", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.35", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.9.6", "versionType": "semver", "lessThanOrEqual": "6.9.*"}, {"status": "unaffected", "version": "6.10", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/scsi/mpt3sas/mpt3sas_base.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/e9bce7c751f6d6c7be88c0bc081a66aaf61a23ee"}, {"url": "https://git.kernel.org/stable/c/19649e49a6df07cd2e03e0a11396fd3a99485ec2"}, {"url": "https://git.kernel.org/stable/c/0081d2b3ae0a17a86b8cc0fa3c8bdc54e233ba16"}, {"url": "https://git.kernel.org/stable/c/521f333e644c4246ca04a4fc4772edc53dd2a801"}, {"url": "https://git.kernel.org/stable/c/46bab2bcd771e725ff5ca3a68ba68cfeac45676c"}, {"url": "https://git.kernel.org/stable/c/9079338c5a0d1f1fee34fb1c9e99b754efe414c5"}, {"url": "https://git.kernel.org/stable/c/18abb5db0aa9b2d48f7037a88b41af2eef821674"}, {"url": "https://git.kernel.org/stable/c/4254dfeda82f20844299dca6c38cbffcfd499f41"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: mpt3sas: Avoid test/set_bit() operating in non-allocated memory\n\nThere is a potential out-of-bounds access when using test_bit() on a single\nword.
