No network or adjacent-network input reaches this code.\nAC:L - The stale `hba->bsg_queue` pointer is created unconditionally on every teardown — there is no error path to hit, no race to win, and no memory-layout precondition the attacker cannot influence; reclaiming the freed `request_queue`/`bsg_set` slab is a standard heap spray the attacker drives, and an open bsg fd lets the attacker choose when the object is actually freed.\nPR:L - Consistent with how this database scores driver-teardown and \"set pointer to NULL after free\" UAFs, a low-privileged local account able to drive device/driver lifecycle events is sufficient; no authentication beyond ordinary local access to the UFS host's lifecycle and bsg endpoint is assumed.\nUI:N - The teardown sequence is performed by the attacker itself (unbind/unload) or happens autonomously during device removal; no victim must mount a filesystem, open a file, or take any other action.\nS:U - The freed `struct request_queue` and `struct bsg_set` and all consequences of dereferencing them stay within the kernel's own security authority, with no crossing into a hypervisor, IOMMU, or other separate scope.\nC:H - Re-entry through the dangling pointer reads `q->tag_set` from freed memory and follows `bset->bd` into `bd->queue->disk` and `cdev_device_del()`, so reclaimed heap contents are interpreted as kernel structures, giving attacker-directed pointer dereferences and disclosure of arbitrary kernel memory.\nI:H - The freed `struct bsg_set` contains the `job_fn` and `timeout_fn` function pointers and the `bd` device pointer, and the reuse path performs `put_device()` (refcount decrement plus release-callback indirect call) and a second `kfree(bset)`, so heap spraying the reclaimed allocation yields write and control-flow-hijack primitives.\nA:H - Use-after-free and double-free on the request queue and bsg set reliably produce slab corruption, a kernel oops, or a panic, which on a UFS-backed Android phone or embedded system means loss of the primary storage controller and of the machine." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
