Vulnerabilities > CVE-2021-4048 - Out-of-bounds Read vulnerability in multiple products

An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack through version 3.10.0, as also used in OpenBLAS before version 0.3.18. Specially crafted inputs passed to these functions could cause an application using lapack to crash or possibly disclose portions of its memory.

Common Weakness Enumeration (CWE)

CWE-125 - Out-of-bounds Read

Common Attack Pattern Enumeration and Classification (CAPEC)

Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
