Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: s390/mm: Add NULL pointer check to crst_table_free() base_crst_free() crst_table_free() used to work with NULL pointers before the conversion to ptdescs. Since crst_table_free() can be called with a NULL pointer (error handling in crst_table_upgrade() add an explicit check. Also add the same check to base_crst_free() for consistency reasons. In real life this should not happen, since order two GFP_KERNEL allocations will not fail, unless FAIL_PAGE_ALLOC is enabled and used.

              "value": "AV:L - The vulnerable path is entered only through a local `mmap()`/`mremap()`/`shmat()` syscall on s390, via `arch_get_unmapped_area()` \u2192 `check_asce_limit()` \u2192 `crst_table_upgrade()`. No network, adjacent-network, or remote-peer data reaches this code.\nAC:L - The attacker fully controls the address-space geometry needed (two ordinary high-address mmaps drive `asce_limit` to `_REGION1_SIZE` and then request a 5-level upgrade, leaving `p4d == NULL`), and can engineer the required order-2 `GFP_KERNEL` failure by driving their own multithreaded process into the OOM-victim state that makes `__alloc_pages_slowpath()` return NULL, retrying as often as needed. Every attempt is cheap and repeatable, so the remaining timing window is one the attacker creates rather than one beyond their control.\nPR:L - Any unprivileged local user can call `mmap()` with a high address hint \u2014 there is no capability check, namespace requirement, or privileged device node anywhere between the syscall entry and `crst_table_free()`. On IBM Z / LinuxONE hosts this means any shared-tenant, container, or shell user.\nUI:N - The whole sequence is performed by the attacking process itself through ordinary syscalls; no victim must mount a filesystem, open a device, or take any other action.\nS:U - The corrupted page-allocator state and the freed reserved page remain entirely within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - On 6.6.y the reserved PFN 0 (the s390 absolute-zero lowcore holding restart PSWs and `restart_fn`/`restart_data` kernel pointers plus machine-check save areas) is released into the buddy allocator with the sanity checks compiled out, so it can be handed to an attacker-influenced allocation still containing that firmware/kernel state; repeating the trigger underflows the refcount of whatever page then occupies PFN 0, yielding a use-after-free read primitive over live kernel memory.\nI:H - Injecting a memblock-reserved page into the buddy free lists breaks the allocator\u0027s ownership invariant \u2014 the page is concurrently written by hardware/firmware (store status, machine-check save area) while owned by another kernel object or user mapping \u2014 and the refcount underflow on repeat triggers gives a double-free/page-reuse primitive, the classic route to controlled kernel writes.\nA:H - On 6.9/6.10 the underflowed `__pa(0)` produces a wild `struct page *` that faults in `compound_order()`, oopsing the kernel; on 6.6.y with page-checking enabled it produces a \"BUG: Bad page state\" splat and `TAINT_BAD_PAGE` (a panic under `panic_on_taint`), and with checks off the corrupted allocator state leads to subsequent oops/panic."
