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":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/ufs/core/ufs_bsg.c"],"versions":[{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"bb4783c670180b922267222408e1c48d22dfbb46","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"22018622e1e9e371198dbd983af946a844d5924c","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"5e7b6e44468c3242c21c2a8656d009fb3eb50a73","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"5f782d4741bf558def60df192b858b0efc6a5f0a","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"88a01e9c9ad40c075756ba93b47984461d4ff15d","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"9193bdc170cc23fe98aca71d1a63c0bf6e1e853b","status":"affected","versionType":"git"},{"version":"df032bf27a414acf61c957ec2fad22a57d903b39","lessThan":"1e95c798d8a7f70965f0f88d4657b682ff0ec75f","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/ufs/core/ufs_bsg.c"],"versions":[{"version":"4.20","status":"affected"},{"version":"0","lessThan":"4.20","status":"unaffected","versionType":"semver"},{"version":"5.10.237","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.181","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.129","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.79","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.16","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13.4","lessThanOrEqual":"6.13.*","status":"unaffected","versionType":"semver"},{"version":"6.14","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":"4.20","versionEndExcluding":"5.10.237"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.15.181"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.1.129"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.6.79"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.12.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.13.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.14"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bb4783c670180b922267222408e1c48d22dfbb46"},{"url":"https://git.kernel.org/stable/c/22018622e1e9e371198dbd983af946a844d5924c"},{"url":"https://git.kernel.org/stable/c/5e7b6e44468c3242c21c2a8656d009fb3eb50a73"},{"url":"https://git.kernel.org/stable/c/5f782d4741bf558def60df192b858b0efc6a5f0a"},{"url":"https://git.kernel.org/stable/c/88a01e9c9ad40c075756ba93b47984461d4ff15d"},{"url":"https://git.kernel.org/stable/c/9193bdc170cc23fe98aca71d1a63c0bf6e1e853b"},{"url":"https://git.kernel.org/stable/c/1e95c798d8a7f70965f0f88d4657b682ff0ec75f"}],"title":"scsi:
