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-2025-22036 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2025-22036/ (Markdown: https://insights.sbomify.com/CVE-2025-22036/index.md)","id":"CVE-2025-22036","markdown":"https://insights.sbomify.com/CVE-2025-22036/index.md","name":"CVE-2025-22036","record":{"aliases":["ALSA-2025:10854","BELL-CVE-2025-22036","DEBIAN-CVE-2025-22036","GHSA-4hwj-3ppp-cx8v","RHSA-2025:10854","RLSA-2025:10854","ROOT-OS-UBUNTU-2404-CVE-2025-22036","UBUNTU-CVE-2025-22036"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel exFAT","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel exFAT driver causes stack corruption via use-after-free, potentially allowing local attackers to execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"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":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"},{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nexfat: fix random stack corruption after get_block\n\nWhen get_block is called with a buffer_head allocated on the stack, such\nas do_mpage_readpage, stack corruption due to buffer_head UAF may occur in\nthe following race condition situation.\n\n     \u003cCPU 0\u003e                      \u003cCPU 1\u003e\nmpage_read_folio\n  \u003c\u003cbh on stack\u003e\u003e\n  do_mpage_readpage\n    exfat_get_block\n      bh_read\n        __bh_read\n\t  get_bh(bh)\n          submit_bh\n          wait_on_buffer\n                              ...\n                              end_buffer_read_sync\n                                __end_buffer_read_notouch\n                                   unlock_buffer\n          \u003c\u003ckeep going\u003e\u003e\n        ...\n      ...\n    ...\n  ...\n\u003c\u003cbh is not valid out of mpage_read_folio\u003e\u003e\n   .\n   .\nanother_function\n  \u003c\u003cvariable A on stack\u003e\u003e\n                                   put_bh(bh)\n                                     atomic_dec(bh-\u003eb_count)\n  * stack corruption here *\n\nThis patch returns -EAGAIN if a folio does not have buffers when bh_read\nneeds to be called.
