AI-suggested

Red Hat has released official security updates for Red Hat Enterprise Linux versions 9 and 10 that address this vulnerability. Users should apply these updates as described in the Red Hat advisories (RHSA-2026:28911 for RHEL 9 and RHSA-2026:33124 for RHEL 10). Applying these patches will remediate the heap buffer under-read issue in the GNU Coreutils sort utility. No additional mitigation steps are indicated by the vendor.

Description

A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
