- `register_intc_controller()` is SuperH platform interrupt-controller boot code with no network, packet, or remote-peer input; the only user-visible surface tied to the freed object is the local sysfs attribute `/sys/devices/system/intc/intc.N/name` and local suspend/resume activity, so exposure is confined to the local system.\nAC:H - The dangling list entry is created only when a `GFP_NOWAIT`/`kcalloc` allocation or `ioremap()` fails inside an `__init` function during early boot, before userspace exists, so the triggering memory-pressure condition is entirely outside any attacker's influence, and it additionally requires SuperH hardware with `CONFIG_SH_INTC`.\nPR:N - No privileges or credentials are involved at any point — the freed `intc_desc_int` is dereferenced by the kernel itself at `device_initcall` time (`register_intc_devs()`) long before any login, and the resulting sysfs `name` attribute that reads the freed object is world-readable (`S_IRUGO`).\nUI:N - Once the error path executes, the stale list entry is dereferenced automatically during the remainder of boot and on every subsequent suspend/resume cycle; no victim action is needed.\nS:U - The use-after-free is confined to kernel heap objects managed by the SH interrupt-controller driver; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - The freed `intc_desc_int` is read back after release — `show_intc_name()` dereferences `d->chip.name` from freed slab memory through a world-readable sysfs file, and list traversal reads `d->list.next` out of reallocated memory, so reclaimed heap contents can be disclosed.\nI:H - `register_intc_devs()` performs `device_register(&d->dev)` on the freed object, writing kobject/device state into reclaimed slab memory and linking it into driver-core lists, which is a write primitive into attacker-influenceable reused heap; per UAF guidance this is High.\nA:H - Traversing `intc_list` through a freed `list_head` follows a stale/overwritten `next` pointer into arbitrary memory, producing an oops or panic, and it corrupts the suspend/resume syscore paths for the interrupt controller."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/sh/intc/core.c"],"versions":[{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"3c7c806b3eafd94ae0f77305a174d63b69ec187c","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"d8de818df12d86a1a26a8efd7b4b3b9c6dc3c5cc","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"971b4893457788e0e123ea552f0bb126a5300e61","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"c3f4f4547fb291982f5ef56c048277c4d5ccc4e4","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"c43df7dae28fb9fce96ef088250c1e3c3a77c527","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"b8b84dcdf3ab1d414304819f824b10efba64132c","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"6ba6e19912570b2ad68298be0be1dc779014a303","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"588bdec1ff8b81517dbae0ae51c9df52c0b952d3","status":"affected","versionType":"git"},{"version":"2dcec7a988a1895540460a0bf5603bab63d5a3ed","lessThan":"63e72e551942642c48456a4134975136cdcb9b3c","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/sh/intc/core.c"],"versions":[{"version":"2.6.30","status":"affected"},{"version":"0","lessThan":"2.6.30","status":"unaffected","versionType":"semver"},{"version":"4.19.325","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.287","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.231","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.174","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.120","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.64","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.11","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12.2","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","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":"2.6.30","versionEndExcluding":"4.19.325"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"5.4.287"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"5.10.231"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"5.15.174"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.1.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.6.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.11.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.12.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.30","versionEndExcluding":"6.13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3c7c806b3eafd94ae0f77305a174d63b69ec187c"},{"url":"https://git.kernel.org/stable/c/d8de818df12d86a1a26a8efd7b4b3b9c6dc3c5cc"},{"url":"https://git.kernel.org/stable/c/971b4893457788e0e123ea552f0bb126a5300e61"},{"url":"https://git.kernel.org/stable/c/c3f4f4547fb291982f5ef56c048277c4d5ccc4e4"},{"url":"https://git.kernel.org/stable/c/c43df7dae28fb9fce96ef088250c1e3c3a77c527"},{"url":"https://git.kernel.org/stable/c/b8b84dcdf3ab1d414304819f824b10efba64132c"},{"url":"https://git.kernel.org/stable/c/6ba6e19912570b2ad68298be0be1dc779014a303"},{"url":"https://git.kernel.org/stable/c/588bdec1ff8b81517dbae0ae51c9df52c0b952d3"},{"url":"https://git.kernel.org/stable/c/63e72e551942642c48456a4134975136cdcb9b3c"}],"title":"sh:
