CVE-2026-42015: Off-by-one Error
A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.
AI Analysis
Technical Summary
An off-by-one error in the PKCS#12 bag element bounds check in the gnutls library on Red Hat Enterprise Linux 10 allows a remote attacker to write beyond the internal array boundary when appending to a PKCS#12 bag with 32 elements. This memory corruption vulnerability can cause denial of service or other unspecified impacts. The issue is tracked as CVE-2026-42015 with a CVSS 3.1 base score of 5.3 (medium severity). Red Hat has released security advisories (RHSA-2026:13274 and RHSA-2026:20611) describing updates to gnutls packages, primarily for Red Hat Hardened Images and Red Hat Enterprise Linux 8, but no explicit fixed version or patch details for Red Hat Enterprise Linux 10 are provided in the input.
