Linux kernel vulnerabilitiesAnd the versions its exploited flaws hit.
Linux kernel is made by Linux. We track 12,101 published vulnerabilities listed under that exact name, across 5,163 versions. 74 of them are on the list of flaws known to be exploited, the newest added on 28 October 2026. Linux lists newer releases under their own names, such as Linux Kernel I40e/i40evf, so check those pages too.
The most recent Linux kernel flaw added to the known-exploited list is CVE-2026-46300, on 28 October 2026. We keep watching the known-exploited list.
Is Linux kernel listed under other names? Yes.
Linux also lists Linux kernel under more specific names, such as Linux Kernel I40e/i40evf and Linux Kernel Ixgbe. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
Which versions of Linux kernel do the exploited flaws hit?
Each exploited flaw lists the versions it affects, usually as ranges. "5.11 to before 5.15.208" means from 5.11 up to, but not including, 5.15.208. Find your version, then patch.

1 flaw being exploited affects software Acme tracks
Linux Kernel contains a missing initialization of a variable vulnerability that could allow for unintended modification of page-cache-backed data via failure to preserve the shared-fragment marker during socket buffer coalescing, causing ESP input processing to decrypt shared fragments in place. This vulnerability can be chained with CVE-2026-109618 and CVE-2026-109619 to implant PHP webshells and run commands as root.
