CVE-2026-6845: NULL Pointer Dereference in Red Hat Red Hat Enterprise Linux 10
CVE-2026-6845 is a vulnerability in the binutils package, specifically in the readelf utility on Red Hat Enterprise Linux 10. It allows a local attacker to cause a Denial of Service (DoS) by processing a specially crafted ELF file, leading to a NULL pointer dereference. This results in system unresponsiveness or program crashes due to excessive resource consumption. The vulnerability requires local access and user interaction to exploit. The CVSS score is 5. 0, indicating medium severity. No official patch or remediation level has been confirmed from the vendor advisory at this time.
AI Analysis
Technical Summary
This vulnerability involves a NULL pointer dereference in the readelf utility of binutils on Red Hat Enterprise Linux 10. A local attacker can exploit this by tricking a user into processing a malicious ELF file, causing a denial of service through resource exhaustion or application crash. The attack vector requires local access with low privileges and user interaction. The vulnerability does not impact confidentiality or integrity but affects availability. The vendor advisory does not currently specify any patch or mitigation status.
Potential Impact
Successful exploitation leads to denial of service by crashing the readelf utility or causing the system to become unresponsive due to excessive resource consumption. There is no impact on confidentiality or integrity. The attack requires local access and user interaction, limiting the scope of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-6845 for current remediation guidance. Until an official fix is available, avoid processing untrusted ELF files with the readelf utility. No vendor-provided mitigation or temporary fix is currently documented.
