CVE-2024-42147: crypto: hisilicon/debugfs - Fix debugfs uninit process issue

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.23% (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 7fc8d9a525b5c3f8dfa5ed50901e764d8ede7e1e, 8be0913389718e8d27c4f1d4537b5e1b99ed7739, e0a2d2df9ba7bd6bd7e0a9b6a5e3894f7e8445b3.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 7fc8d9a525b5c3f8dfa5ed50901e764d8ede7e1e, 8be0913389718e8d27c4f1d4537b5e1b99ed7739, e0a2d2df9ba7bd6bd7e0a9b6a5e3894f7e8445b3 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: crypto: hisilicon/debugfs - Fix debugfs uninit process issue During the zip probe process, the debugfs failure does not stop the probe. When debugfs initialization fails, jumping to the error branch will also release regs, in addition to its own rollback operation. As a result, it may be released repeatedly during the regs uninit process. Therefore, the null check needs to be added to the regs uninit process.
