CVE-2026-74583
A flaw was found in the Linux kernel's net/sched: clsroute component. A race condition exists in the route4 classifier's fastmap cache, where a reader can re-cache a pointer to a filter that has already been freed by a writer. This can lead to a use-after-free condition, allowing subsequent packe...
CVE-2026-74583
In the Linux kernel, the following vulnerability has been resolved: net/sched: clsroute: fix fastmap use-after-free on filter The route4 classifier maintains a 16-slot fastmap cache that stores raw struct route4filter pointers indexed by id, iif. The reader route4classify populates this cache via...
CVE-2026-74583
CVE-2026-74583 is a use-after-free race condition in the Linux kernel's cls_route classifier (route4 fastmap cache). The route4_set_fastmap() reader can write a filter pointer into the 16-slot fastmap cache after a concurrent writer (route4_delete/route4_change) has already cleared it via route4_...
