An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3497 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-3497/ (Markdown: https://insights.sbomify.com/CVE-2026-3497/index.md)","id":"CVE-2026-3497","markdown":"https://insights.sbomify.com/CVE-2026-3497/index.md","name":"CVE-2026-3497","record":{"aliases":["ALSA-2026:6461","ALSA-2026:6462","ALSA-2026:6463","CLSA-2026-1774366569","CLSA-2026-1774369958","CLSA-2026-1775220882","CLSA-2026-1775752680","CLSA-2026-1777455730","CLSA-2026-1777950533","DEBIAN-CVE-2026-3497","ECHO-09c4-31b3-a9b0","GHSA-wcpp-3x59-h8vp","RHSA-2026:10714","RHSA-2026:13750","RHSA-2026:14924","RHSA-2026:15891","RHSA-2026:15893","RHSA-2026:6461","RHSA-2026:6462","RHSA-2026:6463","RHSA-2026:7107","RHSA-2026:9415","RHSA-2026:9732","RLSA-2026:6461","RLSA-2026:6462","RLSA-2026:6463","UBUNTU-CVE-2026-3497"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSH GSSAPI patch","requires_auth":"none","summary":"Attackers can trigger undefined behavior via uninitialized memory access in GSSAPI key exchange, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"openssh","vendor":"openbsd"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-824","name":"Access of Uninitialized Pointer"},{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.","ecosystems":["AlmaLinux:10","AlmaLinux:8","AlmaLinux:9","Red Hat:enterprise_linux:10.1","Red
