This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service. ## Affected - `libsolv = 0.7.36` - `hardened_images` - `openshift_container_platform = 4.0` - `satellite = 6.0` - `update_infrastructure = 4` - `enterprise_linux = 7.0` - `enterprise_linux = 8.0` - `enterprise_linux = 9.0` - `enterprise_linux = 10.0` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Vendor advisories - **RHSA-2026:49775** · Red Hat · fixed in: Red Hat Enterprise Linux Server (v. 7 ELS), Red Hat Enterprise Linux Server Optional (v. 7 ELS) · released 2026-08-03 · [advisory](https://access.redhat.com/errata/RHSA-2026:49775) - **RHSA-2026:59831** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.12 · released 2026-09-03 · [advisory](https://access.redhat.com/errata/RHSA-2026:59831) - **RHSA-2026:50223** · Red Hat · fixed in: Red Hat Satellite 6.16 for RHEL 8 · released 2026-08-04 · [advisory](https://access.redhat.com/errata/RHSA-2026:50223) - **RHSA-2026:65839** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.13 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:65839) - **RHSA-2026:56786** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.14 · released 2026-08-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:56786) - **RHSA-2026:56911** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.15 · released 2026-08-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:56911) - **RHSA-2026:56853** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.16 · released 2026-08-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:56853) - **RHSA-2026:60019** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.17 · released 2026-09-03 · [advisory](https://access.redhat.com/errata/RHSA-2026:60019) - **RHSA-2026:57483** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.18 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:57483) - **RHSA-2026:57402** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.19 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:57402) - **RHSA-2026:48818** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0), Red Hat Enterprise Linux BaseOS EUS (v. 10.0), Red Hat Enterprise Linux CodeReady Linux Builder EUS (v. 10.0) · released 2026-07-31 · [advisory](https://access.redhat.com/errata/RHSA-2026:48818) - **Red Hat VEX** · Moderate · affected: Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat OpenShift Container Platform 4 · updated 2026-09-17 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-48864.json)
