CVE-2024-2961
Published: 17 April 2024
Summary
CVE-2024-2961 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Netapp Hci Compute Node. Its CVSS base score is 7.3 (High).
Operationally, ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a buffer overflow in the iconv() function of the GNU C Library (glibc) in versions 2.39 and earlier. When converting input strings to the ISO-2022-CN-EXT character set, the function can write up to four bytes beyond the end of the caller-supplied output buffer, classified under CWE-787. This flaw received a CVSS 3.1 score of 7.3 with a local attack vector, no privileges required, and impacts that include limited confidentiality and integrity loss alongside high availability impact.
An unauthenticated local attacker can trigger the overflow by supplying a malicious string to any application that invokes iconv() for the affected charset conversion. Successful exploitation may crash the process or corrupt an adjacent variable, potentially allowing limited control over program behavior without network access or user interaction.
Public discussion and patch information appear in the referenced oss-security postings from April and May 2024, which address coordinated disclosure and distribution updates for glibc. The associated EPSS score has remained high, reaching a peak of 0.9292 with a current value of 0.9192, indicating sustained exploitation interest following disclosure.
