Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Fixed version: Linux Linux 1875de656370c89b99a150d220df876288ee0344, 5d476bb76b7d72d8b7ed04a9c614900b097e3af7, 9504c8b6644f3c8799206c2e2840260bd416f341; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.159.1-1 on Azure Linux 3.0 Release Notes.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1875de656370c89b99a150d220df876288ee0344, 5d476bb76b7d72d8b7ed04a9c614900b097e3af7, 9504c8b6644f3c8799206c2e2840260bd416f341; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.159.1-1 on Azure Linux 3.0 Release Notes or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe() In wmt_i2c_probe(), i2c->clk is acquired using of_clk_get(). If any subsequent operation fails or when the module is unloaded, the clock reference count is never decremented via clk_put(), leading to a resource leak. Switch to devm_clk_get() so that the clock is automatically managed and released.
