Detectable: no evidence on record.
No public nuclei template indexed

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.

Description

In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp-mach-common: Add missing error check for clock acquisition The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not check the return values of clk_get(). This could lead to a kernel crash when the invalid pointers are later dereferenced by clock core functions. Fix this by: 1. Changing clk_get() to the device-managed devm_clk_get(). 2. Adding IS_ERR() checks immediately after each clock acquisition.
