{"identifier":"CVE-2026-99267","cve":{"id":"CVE-2026-99267","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/napi: make stale entries time out after 60s\n\nWith dynamic tracking a NAPI id that hasn't been seen for a minute is\nmeant to be dropped from the list the ring busy polls. The timeout is\nadded to jiffies, but it is defined as 60 * SEC_CONVERSION, and\nSEC_CONVERSION isn't the number of jiffies in a second. It is the\ninternal factor of __timespec64_to_jiffies(), HZ scaled up by\nSEC_JIFFIE_SC bits. For HZ=1000 that is 1000 << 22, which puts the\ntimeout at about eight years. On 32-bit the multiplication overflows.\n\nSo entries are never removed, and every id that a socket of the ring\never had keeps being polled on each wait.","published":"2026-11-03T12:17:33.860000+00:00","modified":"2026-11-03T20:18:32.400000+00:00","status":"Received","score":null,"severity":"UNSCORED","vector":"","cvss_version":"","affected":[],"weaknesses":[],"references":[{"url":"https://git.kernel.org/stable/c/18c373f446068972788158c8c7de6e849b04ed98","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/3fe820cf35f83534eab72ea73f1a83cfd3cd8079","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/981621d6eadcd232d4ea748aaeb046337f10d3c1","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/9c151648780d89e5446e5f89f3fa2e416c3bb911","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}],"kev":null,"kev_checked":true,"metrics":{},"configurations":[],"source":"nvd","retrieved_at":"2026-11-03T23:31:59.306936+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence.","Fresh EPSS data is unavailable; missing values are not zero."]},"epss":null,"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"git.kernel.org","source_url":"https://git.kernel.org/stable/c/18c373f446068972788158c8c7de6e849b04ed98","investigate_url":"https://investigate.aeglixmind.com/#git.kernel.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-99267","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-99267","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-99267","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
