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-2023-53315 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-2023-53315/ (Markdown: https://insights.sbomify.com/CVE-2023-53315/index.md)","id":"CVE-2023-53315","markdown":"https://insights.sbomify.com/CVE-2023-53315/index.md","name":"CVE-2023-53315","record":{"aliases":["BELL-CVE-2023-53315","DEBIAN-CVE-2023-53315","GHSA-fv7c-cvj6-wrfg","UBUNTU-CVE-2023-53315"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A memory corruption flaw in the ath11k WiFi driver causes kernel crashes when processing invalid RX descriptors, 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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath11k: Fix SKB corruption in REO destination ring\n\nWhile running traffics for a long time, randomly an RX descriptor\nfilled with value \"0\" from REO destination ring is received.\nThis descriptor which is invalid causes the wrong SKB (SKB stored in\nthe IDR lookup with buffer id \"0\") to be fetched which in turn\ncauses SKB memory corruption issue and the same leads to crash\nafter some time.\n\nChanged the start id for idr allocation to \"1\" and the buffer id \"0\"\nis reserved for error validation.
