CVE-2024-50076: vt: prevent kernel-infoleak in con_font_get()

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.60% (FIRST EPSS).
  • Anyone who can reach it over the internet 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 1e5a17dc77d8a8bbe67040b32e2ef755901aba44, 23c4cb8a56978e5b1baa171d42e616e316c2039d, adb1f312f38f0d2c928ceaff089262798cc260b4.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1e5a17dc77d8a8bbe67040b32e2ef755901aba44, 23c4cb8a56978e5b1baa171d42e616e316c2039d, adb1f312f38f0d2c928ceaff089262798cc260b4 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: vt: prevent kernel-infoleak in con_font_get() font.data may not initialize all memory spaces depending on the implementation of vc->vc_sw->con_font_get. This may cause info-leak, so to prevent this, it is safest to modify it to initialize the allocated memory space to 0, and it generally does not affect the overall performance of the system.
