CVE-2026-74580

A flaw was found in the Linux kernel's vhost subsystem. A local attacker could exploit this vulnerability by reconfiguring a virtual ring vring using specific ioctl commands while a device Input/Output Memory Management Unit IOTLB is attached. This improper handling of the vring metadata cache ca...

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...

AZL-96998 CVE-2026-74583 affecting package kernel for versions less than 6.6.152.1-1

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...
