probe (`hda_codec_driver_probe` → `patch_vt1718S`/`patch_vt2002P`/`patch_vt1812`/`patch_vt3476` → `add_secret_dac_path`), reached via local driver bind/module autoload on systems with affected VIA codecs—not via network or remote peer input.\nAC:L - An attacker can force `snd_hda_get_connections()` to fail with `-ENOMEM` by exhausting memory before codec bind/autoload (same pattern as CVE-2023-52999), and VIA codecs with analog DAC widgets then hit the `conn[nums++]=nid` path deterministically; no uncontrollable race is required.\nPR:L - Direct sysfs rebind needs root, but an unprivileged audio-capable user can trigger ALSA lazy module autoload (`/dev/aloadC*` → `request_module` of the VIA codec driver) as in CVE-2025-68205, and a local account is enough to leverage boot-time probe corruption.\nUI:N - Codec probe is system-driven (boot bind or attacker-initiated autoload); no separate victim must open a file, mount media, or otherwise interact.\nS:U - The stack underflow corrupts kernel stack memory in the same host kernel authority; this is not a VM escape, IOMMU bypass, or sandbox boundary cross.\nC:H - When `nums` is a negative error code, `conn[nums++]=nid` is a stack out-of-bounds write; under scoring guidance, OOB write memory corruption is treatable as High confidentiality impact (same treatment as CVE-2023-52999).\nI:H - The bug is a stack out-of-bounds write of a widget NID below the on-stack `conn[8]` array, which is memory-corruption integrity impact and can corrupt frame/control data for control-flow hijack; OOB write scores High.\nA:H - Stack corruption from the negative-index write (and continued probe with a corrupted frame, since callers ignore `add_secret_dac_path()`’s return) can produce an oops/panic; any kernel crash is High availability impact." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
