Title
ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup
Use the control private_free callback to free the associated data
block. This ensures that the memory won't leak, whatever way the
control gets destroyed.
The original implementation didn't actually remove the ALSA
controls in hda_cs_dsp_control_remove(). It only freed the internal
tracking structure. This meant it was possible to remove/unload the
amp driver while leaving its ALSA controls still present in the
soundcard. Obviously attempting to access them could cause segfaults
or at least dereferencing stale pointers.

"value": "AV:L - The vulnerable code is reached through ioctls (SNDRV_CTL_IOCTL_ELEM_READ/WRITE/INFO) on the local ALSA control device /dev/snd/controlC*, requiring local system access. There is no network-facing component in sound/pci/hda/hda_cs_dsp_ctl.c.\nAC:L - Once the amp driver is unbound the dangling kcontrol persists indefinitely on the sound card, so there is no race to win \u2014 the attacker freely grooms the kmalloc-32/kmalloc-192 slabs to reclaim the freed hda_cs_dsp_coeff_ctl and cs_dsp_coeff_ctl, then triggers the dereference at a time of their choosing, repeatably. Cirrus CS35L41/CS35L56 amps are present on a very large population of current laptops, so the affected configuration is common rather than exotic.\nPR:L - Exploitation only requires the ability to open /dev/snd/controlC* and issue element read/write ioctls, which snd_ctl_elem_read()/snd_ctl_elem_write() perform with no capability check \u2014 any local user in the audio group or with an active logind session qualifies. No root or CAP_SYS_ADMIN is needed to reach the use-after-free.\nUI:N - The attacker performs the entire exploit themselves with ioctls on the stale control; no victim needs to open a file, mount a filesystem, or otherwise interact. The driver-unbind that leaves the stale control behind is an ambient system state (module update, driver reload, codec rebind), not an action the attacker must social-engineer a victim into performing during the attack.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed. Standard kernel-local privilege escalation keeps the scope unchanged.\nC:H - After reclaiming the freed cs_dsp_coeff_ctl the attacker controls ctl-\u003ecache and ctl-\u003elen, and cs_dsp_coeff_read_ctrl() does memcpy(buf, ctl-\u003ecache + off*4, len) into the control value buffer, which snd_ctl_ioctl_elem_read() copies straight to userspace \u2014 an arbitrary kernel memory read primitive.\nI:H - cs_dsp_coeff_write_ctrl() does memcpy(ctl-\u003ecache + off*4, buf, len) with an attacker-controlled destination pointer and attacker-supplied data, giving an arbitrary kernel write; additionally the stale kcontrol\u0027s get/put/info function pointers reference the unloaded snd-hda-cs-dsp-ctls module text, allowing indirect control-flow hijack into freed executable memory.\nA:H - Even without successful heap grooming, dereferencing the freed hda_cs_dsp_coeff_ctl and cs_dsp_coeff_ctl, taking a mutex on freed memory, and calling into unloaded module text reliably produces an oops or panic. Any unprivileged user with audio access can crash the machine on demand."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
