This ensures existing cgroup\nmemory limits apply and prevents uncontrolled kernel memory growth without\nintroducing additional policy or per-file limits.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e2f5d2ea479b9b2619965d43db70939589afe43a"},{"fixed":"b6117210ed349356f8e6027ff020b4d620bca42b"},{"fixed":"815fa29cab3c67bebb9d0b5f41145cdd3a14d04d"},{"fixed":"866e0c1a9e7244d58ed74853cb22b81e1900cfdd"},{"fixed":"bbfaa5761f589a81031b493cb01275a990d6fb25"},{"fixed":"8e1664b9ee43608eb973d357ae5d858d30cbc9ca"},{"fixed":"cb8b9a1755fe9f38e4fb7f287486d7e7fab3dba4"},{"fixed":"405fd652d8fedff219a8f48daf8f20e881e303ab"},{"fixed":"26b4309a3ab82a0697751cde52eb336c29c19035"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43287.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"5.10.252"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.202"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43287.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/26b4309a3ab82a0697751cde52eb336c29c19035"},{"type":"WEB","url":"https://git.kernel.org/stable/c/405fd652d8fedff219a8f48daf8f20e881e303ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/815fa29cab3c67bebb9d0b5f41145cdd3a14d04d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/866e0c1a9e7244d58ed74853cb22b81e1900cfdd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e1664b9ee43608eb973d357ae5d858d30cbc9ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6117210ed349356f8e6027ff020b4d620bca42b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbfaa5761f589a81031b493cb01275a990d6fb25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb8b9a1755fe9f38e4fb7f287486d7e7fab3dba4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43287.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43287"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43287.json"}}
