kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...

CVE-2026-53014

A flaw was found in the Linux kernel. When the kernel's traffic control TC subsystem processes network packets for redirection across different types of network devices, it can incorrectly handle packet headers. This can lead to corruption of network packet data. A local attacker could potentiall...

CVE-2026-53080

A flaw was found in the Linux kernel's traffic control firewall classifier clsfw module. An attacker with the ability to create traffic control filters could exploit a vulnerability where an invalid filter, created using an older method, is processed before proper validation. This can lead to a...

CVE-2026-53264 net/sched: act_api: use RCU with deferred freeing for action lifecycle

In the Linux kernel, the following vulnerability has been resolved: net/sched: actapi: use RCU with deferred freeing for action lifecycle When NEWTFILTER and DELFILTER are run concurrently it is possible to create a race with an associated action. Let's illustrate with CPU0 running NEWTFILTER and...
