Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

It was discovered that the clsRoute filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it, if its handle had the value 0...

SUSE 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

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

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_...
