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-2023-53987 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-2023-53987/ (Markdown: https://insights.sbomify.com/CVE-2023-53987/index.md)","id":"CVE-2023-53987","markdown":"https://insights.sbomify.com/CVE-2023-53987/index.md","name":"CVE-2023-53987","record":{"aliases":["BELL-CVE-2023-53987","DEBIAN-CVE-2023-53987","GHSA-m6qc-r2rx-cm2q","UBUNTU-CVE-2023-53987"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A local attacker can trigger a NULL pointer dereference in the Linux kernel's ping socket handling, causing a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nping: Fix potentail NULL deref for /proc/net/icmp.\n\nAfter commit dbca1596bbb0 (\"ping: convert to RCU lookups, get rid\nof rwlock\"), we use RCU for ping sockets, but we should use spinlock\nfor /proc/net/icmp to avoid a potential NULL deref mentioned in\nthe previous patch.\n\nLet's go back to using spinlock there.\n\nNote we can convert ping sockets to use hlist instead of hlist_nulls\nbecause we do not use SLAB_TYPESAFE_BY_RCU for ping sockets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"ping: Fix potentail NULL deref for /proc/net/icmp.","id":"CVE-2023-53987","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"fs/ntfs3: Fix slab-out-of-bounds read in hdr_delete_de()","id":"CVE-2023-53988"},"packages":[],"prev":{"headline":"mips: bmips: BCM6358: disable RAC flush for TP1","id":"CVE-2023-53986"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A local attacker can trigger a NULL pointer dereference in the Linux kernel's ping socket handling, causing a system crash.","url":"https://insights.sbomify.com/CVE-2023-53987/"}
