A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fix is available and has been applied in the Linux kernel commits listed under fixedVersions. Users and administrators should update their Linux kernel to a version including these fixes to remediate the memory leak.

Description

A memory leak vulnerability was identified and fixed in the Linux kernel's ASoC AMD YC driver, specifically in the acp6x_pdm_dma_close() function. The issue involved failure to free a buffer allocated during acp6x_pdm_dma_open(), potentially leading to resource exhaustion over time.

Impact

The vulnerability causes a memory leak in the affected kernel version, which could lead to increased memory consumption and potential resource exhaustion if the affected function is invoked repeatedly. There is no indication of direct code execution or privilege escalation impact. No known exploits in the wild have been reported.

Summary

The Linux kernel's ASoC AMD YC component contained a memory leak vulnerability in the acp6x_pdm_dma_close() function. This function did not free the runtime->private_data buffer allocated in acp6x_pdm_dma_open(), resulting in unreleased memory. The fix involved adding the missing kfree call to properly release this buffer. The vulnerability affects Linux kernel version 5.16 and was resolved in subsequent commits.
