No network, adjacent, or physical path reaches this code \u2014 the test operates entirely on hardcoded local data.\nAC:L - Within an affected build the use-after-free is reached unconditionally and deterministically every boot, requiring no preparation, no race to win, and no memory-layout grooming. Although CONFIG_VCAP_KUNIT_TEST is a non-default developer option, CVSS scores the vulnerable configuration, and within it the trigger is fully reliable.\nPR:N - The kunit suite runs from late_initcall with kunit.enable defaulting to true, so the freed-object accesses execute with no authentication, no capability check, and no privilege gate of any kind on an affected kernel. No credentials are needed for the vulnerable code path to be taken.\nUI:N - The test suite executes automatically during kernel boot without any victim action such as mounting a filesystem, plugging in a device, or opening a file.\nS:U - The corruption is confined to the kernel\u0027s own slab allocator and the VCAP admin rule list within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free: freed slab memory is read back as list_head and id fields, and if the slab is reallocated between the kfree() and the reads, those reads pull in whatever data now occupies the chunk. Per kernel scoring guidance a UAF gives attacker influence over freed-object contents and is rated High.\nI:H - Beyond the reported UAF read, the retained dangling node in admin-\u003erules leads vcap_del_rule() to perform list_del() writes into freed memory and a second vcap_free_rule(), producing a double-free plus kfree() of pointers read out of freed memory \u2014 an arbitrary-free/write primitive suitable for heap exploitation.\nA:H - The use-after-free and subsequent double-free corrupt slab metadata and will oops or panic the kernel; on a KUnit-enabled kernel, which commonly runs KASAN, this reliably produces a fatal splat during boot."
