It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74595 in the wild and no public exploit code.\n\nAffected product: 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-2026-74595/ (Markdown: https://insights.sbomify.com/CVE-2026-74595/index.md)","id":"CVE-2026-74595","markdown":"https://insights.sbomify.com/CVE-2026-74595/index.md","name":"CVE-2026-74595","record":{"aliases":["AZL-97224","BELL-CVE-2026-74595","DEBIAN-CVE-2026-74595","GHSA-7jrv-8xmf-x8j2","UBUNTU-CVE-2026-74595"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel fscrypt","requires_auth":"low_privilege","summary":"An attacker on an idmapped mount can bypass owner checks to set encryption policies, potentially gaining unauthorized access or privileges.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfscrypt: use the mount idmap for the owner check in fscrypt_ioctl_set_policy()\n\nfscrypt_ioctl_set_policy() calls inode_owner_or_capable() with\n\u0026nop_mnt_idmap before allowing an encryption policy to be set, instead\nof the idmap of the mount the ioctl was issued on.\n\nfscrypt is used by filesystems that support idmapped mounts (e.g. ext4,\nf2fs), so on such a mount this compares the caller's fsuid against the\nunmapped on-disk owner rather than the mapped owner: the actual owner\ncan be wrongly denied with -EACCES and an unrelated caller wrongly\nallowed.
