CVE-2026-14759: radareorg radare2 RBinJava Line Number Table class.c r_bin_java_inner_classes_attr_calc_size heap-based overflow

LowCVSS 1.9 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 7/100)

  • 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: 0.22% (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: radare2 (openSUSE:Leap 16.0) 6.2.2-bp160.1.1.
  • Severity is disputed: the assigning authority (CNA) scores it 4.8, NVD 1.9.

Low priority for now. Upgrade to radare2 (openSUSE:Leap 16.0) 6.2.2-bp160.1.1 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
