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-2026-53346 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-2026-53346/ (Markdown: https://insights.sbomify.com/CVE-2026-53346/index.md)","id":"CVE-2026-53346","markdown":"https://insights.sbomify.com/CVE-2026-53346/index.md","name":"CVE-2026-53346","record":{"aliases":["BELL-CVE-2026-53346","DEBIAN-CVE-2026-53346","GHSA-mp8j-7v82-r69x","UBUNTU-CVE-2026-53346"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A kernel bug causes boot failures and crashes when specific unwind table configurations are enabled, leading to denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nrust: arm64: set uwtable llvm module flag for CONFIG_UNWIND_TABLES\n\nDue to a rustc bug [1] the -Cforce-unwind-tables=y flag only emits the\nuwtable annotation for functions, but not for the module. This means\nthat compiler-generated functions such as 'asan.module_ctor' do not\nreceive the uwtable annotation.\n\nWhen CONFIG_UNWIND_PATCH_PAC_INTO_SCS is enabled, this leads to boot\nfailures because the dwarf information emitted for the kasan\nconstructors is wrong, which causes the SCS boot patching code to\npatch the constructor in an illegal manner. Specifically, the paciasp\ninstruction is patched, but the autiasp instruction is not. This\nmismatch leads to a crash when the constructor is called during boot.\n\n\t==================================================================\n\tBUG: KASAN: global-out-of-bounds in do_basic_setup+0x4c/0x90\n\tRead of size 8 at addr ffffffe3cc7eb488 by task swapper/0/1\n\nSpecifically the faulting instruction is the (*fn)() to invoke the\nconstructor in do_ctors() of the init/main.c file.\n\nOnce the fix lands in rustc, this flag can be made conditional on the\nrustc version.
