CVE-2026-9150: Stack-based Buffer Overflow in Red Hat Red Hat Enterprise Linux 10
A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow in libsolv's Debian metadata parser component within Red Hat Enterprise Linux 10. When the parser processes maliciously crafted Debian repository metadata with specially crafted SHA384 or SHA512 checksum tags, it can trigger memory corruption. This can result in a denial of service condition. The CVSS 3.1 vector indicates the attack requires network access with low complexity, no privileges, and user interaction, impacting availability only. No integrity or confidentiality impacts are noted.
Potential Impact
Successful exploitation leads to memory corruption causing denial of service on the affected system. There is no reported impact on confidentiality or integrity. No known exploits are currently observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-9150 for current remediation guidance. Until an official fix is available, users should exercise caution when processing Debian repository metadata from untrusted sources. No vendor advisory indicates that the issue is already mitigated or that no action is required.
