CVE-2026-14759
Description
A flaw was found in radareorg radare2. A local attacker can perform a manipulation in the RBinJava Line Number Table Parser component, specifically within the r_bin_java_inner_classes_attr_calc_size function. This can lead to a heap-based buffer overflow, resulting in a denial of service.
Statement
This Low impact flaw in radare2's RBinJava Line Number Table Parser allows a local attacker to trigger a heap-based buffer overflow. By manipulating the r_bin_java_inner_classes_attr_calc_size function, an attacker can cause a denial of service. Exploitation requires local access to the system where radare2 is installed.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory
If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
