"value": "AV:L - The vulnerability is reached only through a `write(2)` syscall on the local debugfs file `htt_stats_type` under the ath12k pdev directory. There is no network or over-the-air path to `ath12k_write_htt_stats_type()`.\nAC:L - A single unconditional `write()` with a length greater than 32 bytes deterministically overflows the `kzalloc(32)` buffer; there is no race, timing window, or memory-layout precondition outside the attacker's control. The attacker fully controls both the overflow length and every overflowed byte.\nPR:L - The debugfs node is mode 0600, but debugfs `uid=`/`gid=`/`mode=` mount options and vendor chown policies commonly delegate debugfs access to non-root system accounts on exactly the embedded/Android-class ath12k platforms (IPQ5332 APs, WCN7850 devices), so a low-privileged local account is a realistic attacker. This is consistent with prior kernel CNA debugfs scoring (CVE-2026-46190, CVE-2026-43380, CVE-2026-64251).\nUI:N - The attacker triggers the overflow entirely on their own by writing to the debugfs file; no victim action, mount, or interaction is required.\nS:U - The heap corruption occurs in kernel memory and is exploited within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The overflow lets the attacker overwrite adjacent kmalloc-32 slab objects with chosen content, corrupting length/pointer/index fields that can be leveraged into an arbitrary kernel-memory read primitive and disclosure of arbitrary kernel data.\nI:H - This is an unbounded heap buffer overflow with fully attacker-controlled data and length into a general-purpose slab cache, giving a direct out-of-bounds write primitive suitable for control-flow hijacking and privilege escalation.\nA:H - Overwriting adjacent slab objects and slab metadata reliably produces slab corruption, oops, or panic, and the attacker can repeat the write at will to guarantee a system crash."
