The affected code is driver-core firmware-node plumbing reached only during in-kernel device/driver probe and property lookups on the local machine (gpiolib-swnode, iio/inkern, sfp-bus, reset, mailbox, v4l2-fwnode); no packet, socket or remote peer data ever reaches `software_node_get_reference_args()`.\nAC:H - The faulty bound only differs from the correct one when `prop->length` is not an exact multiple of `sizeof(struct software_node_ref_args)`, and every in-tree `DEV_PROP_REF` property is built by `PROPERTY_ENTRY_REF[_ARRAY[_LEN]]()`, which always sets an exact multiple; the required malformed property table is a condition the attacker cannot create or influence.\nPR:L - If a mis-sized reference property existed, the lookup is driven from ordinary probe/consumer paths that an unprivileged local user can provoke (device binding, opening a consumer device node) without any capability; scored as low privilege rather than high since no root-only interface gates it.\nUI:N - The out-of-bounds element read happens automatically inside the property lookup during device probe or consumer resource acquisition, with no action required from another user.\nS:U - The overread, wild pointer dereference and any resulting crash are confined to the kernel's own security authority on the same host; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 87 bytes of adjacent slab memory beyond the reference array are read and interpreted as a `software_node_ref_args`, and the eight `u64 args[]` values from that out-of-bounds memory are propagated to consumers (GPIO/IIO/reset specifiers) where they can surface, making this more than a strictly bounded few-byte read.\nI:H - The out-of-bounds bytes are type-confused into a live `struct fwnode_handle *` that is dereferenced and invoked through its ops vtable (`fwnode_property_read_u32()`, `fwnode_handle_get()` → `kobject_get()`), giving an indirect call through non-object memory and a refcount increment at an out-of-bounds address — a control-flow-relevant corruption primitive.\nA:H - Reading past the allocation yields a garbage `fwnode` pointer that is immediately dereferenced and called through, producing a kernel oops/panic (and a KASAN slab-out-of-bounds report on instrumented kernels)."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/base/swnode.c"],"versions":[{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"142acd739eb6f08c148a96ae8309256f1422ff4b","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"56ce76e8d406cc72b89aee7931df5cf3f18db49d","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"9324127b07dde8529222dc19233aa57ec810856c","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"f9397cf7bfb680799fb8c7f717c8f756384c3280","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"4b3383110b6df48e0ba5936af2cb68d5eb6bd43b","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"7af18e42bdefe1dba5bcb32555a4d524fd504939","status":"affected","versionType":"git"},{"version":"59abd83672f70cac4b6bf9b237506c5bc6837606","lessThan":"31e4e12e0e9609850cefd4b2e1adf782f56337d6","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/base/swnode.c"],"versions":[{"version":"5.0","status":"affected"},{"version":"0","lessThan":"5.0","status":"unaffected","versionType":"semver"},{"version":"5.10.239","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.186","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.142","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.95","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.35","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.4","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","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":"5.0","versionEndExcluding":"5.10.239"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"5.15.186"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"6.1.142"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"6.6.95"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"6.12.35"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"6.15.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"6.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/142acd739eb6f08c148a96ae8309256f1422ff4b"},{"url":"https://git.kernel.org/stable/c/56ce76e8d406cc72b89aee7931df5cf3f18db49d"},{"url":"https://git.kernel.org/stable/c/9324127b07dde8529222dc19233aa57ec810856c"},{"url":"https://git.kernel.org/stable/c/f9397cf7bfb680799fb8c7f717c8f756384c3280"},{"url":"https://git.kernel.org/stable/c/4b3383110b6df48e0ba5936af2cb68d5eb6bd43b"},{"url":"https://git.kernel.org/stable/c/7af18e42bdefe1dba5bcb32555a4d524fd504939"},{"url":"https://git.kernel.org/stable/c/31e4e12e0e9609850cefd4b2e1adf782f56337d6"}],"title":"software
