CVE-2024-27047: net: phy: fix phy_get_internal_delay accessing an empty array

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.28% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0307cf443308ecc6be9b2ca312bb31bae5e5a7ad, 06dd21045a7e8bc8701b0ebedcd9a30a6325878b, 0e939a002c8a7d66e60bd0ea6b281fb39d713c1a; azl3 hyperv-daemons 6.6.22.1-2 on Azure Linux 3.0 6.6.35.1-1; azl3 hyperv-daemons 6.6.35.1-1 on Azure Linux 3.0 6.6.35.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0307cf443308ecc6be9b2ca312bb31bae5e5a7ad, 06dd21045a7e8bc8701b0ebedcd9a30a6325878b, 0e939a002c8a7d66e60bd0ea6b281fb39d713c1a; azl3 hyperv-daemons 6.6.22.1-2 on Azure Linux 3.0 6.6.35.1-1; azl3 hyperv-daemons 6.6.35.1-1 on Azure Linux 3.0 6.6.35.1-1 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: net: phy: fix phy_get_internal_delay accessing an empty array The phy_get_internal_delay function could try to access to an empty array in the case that the driver is calling phy_get_internal_delay without defining delay_values and rx-internal-delay-ps or tx-internal-delay-ps is defined to 0 in the device-tree. This will lead to "unable to handle kernel NULL pointer dereference at virtual address 0". To avoid this kernel oops, the test should be delay >= 0. As there is already delay < 0 test just before, the test could only be size == 0.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
