Title
scsi: mpt3sas: Avoid test/set_bit() operating in non-allocated memory
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Avoid test/set_bit() operating in non-allocated memory
There is a potential out-of-bounds access when using test_bit() on a single
word. The test_bit() and set_bit() functions operate on long values, and
when testing or setting a single word, they can exceed the word
boundary. KASAN detects this issue and produces a dump:
BUG: KASAN: slab-out-of-bounds in _scsih_add_device.constprop.0 (./arch/x86/include/asm/bitops.h:60 ./include/asm-generic/bitops/instrumented-atomic.h:29 drivers/scsi/mpt3sas/mpt3sas_scsih.c:7331) mpt3sas
Write of size 8 at addr ffff8881d26e3c60 by task kworker/u1536:2/2965
For full log, please look at [1].
Make the allocation at least the size of sizeof(unsigned long) so that
set_bit() and test_bit() have sufficient room for read/write operations
without overwriting unallocated memory.

"value": "AV:L - The undersized bitmaps are per-HBA kernel objects touched by local device-discovery/reset work and by the `MPT3COMMAND` ioctl on `/dev/mpt3ctl`, which passes a user-supplied `device_handle` to `test_bit()`. Nothing here processes remote network data, so local access is required.\nAC:L - On any controller whose firmware reports a `MaxDevHandle` that is not a multiple of 64, the allocation is deterministically short and every device add/remove or handle-referencing ioctl performs the 8-byte read-modify-write past the requested allocation. No race, no memory-layout grooming, and no unpredictable system state is involved.\nPR:L - The driver performs no `capable()`/`CAP_SYS_RAWIO` check on any of these paths \u2014 reachability is governed solely by device-node policy, and appliance, storage-management and container deployments routinely hand `/dev/mpt3ctl` or HBA-attached block devices to a non-root storage group. 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\u0027s 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."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
