The table max_size only\ntells the periodic collector to reclaim entries after the cache has\nalready exceeded the limit. It does not reclaim entries that the\nattacker continues to use.\n\nReject new cache entries once either table reaches max_size * 3 / 2.\nThe extra headroom lets the periodic collector catch up while the\nexisting scheduler fallback continues to use the selected destination\nwhen cache creation fails. New traffic therefore stays serviceable\nwithout growing the tables further.","score":null,"severity":"unknown","published":"2026-10-18T15:51:17.262Z","modified":"2026-10-30T12:40:18.489Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"8b93288b4543ad5139a25a5b211a07bf755652dd","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"f6e9446bfb79907d3092fc45a0054b0c3b329bfe","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"488eaba207dd2e4c5afc65e18dc237d70f01d283","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"bc9ff8e64771cc32a216953fe615386f46ac1eaa","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"31028d7b970962fbeda1e9131405c76551094300","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"6316d17324bd4ca400c26adb7b656c6e3447c209","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"16c83c047ecfaf226ad81d45d77fa11a3184d0e4","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","status":"affected","lessThan":"2a3c3de660f96865f303fd25f1285f2ffbfd521d","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98857"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","status":"unaffected","lessThan":"2.6.12","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98857"}],"remediation":[],"references":["https://git.kernel.org/stable/c/8b93288b4543ad5139a25a5b211a07bf755652dd","https://git.kernel.org/stable/c/f6e9446bfb79907d3092fc45a0054b0c3b329bfe","https://git.kernel.org/stable/c/488eaba207dd2e4c5afc65e18dc237d70f01d283","https://git.kernel.org/stable/c/bc9ff8e64771cc32a216953fe615386f46ac1eaa","https://git.kernel.org/stable/c/31028d7b970962fbeda1e9131405c76551094300","https://git.kernel.org/stable/c/6316d17324bd4ca400c26adb7b656c6e3447c209","https://git.kernel.org/stable/c/16c83c047ecfaf226ad81d45d77fa11a3184d0e4","https://git.kernel.org/stable/c/2a3c3de660f96865f303fd25f1285f2ffbfd521d"],"sources":[{"name":"CVE","id":"CVE-2026-98857","modified":"2026-10-30T12:40:18.489Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98857"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T13:09:57.286Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T02:45:32.518Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
