kernel: net: shaper: rework the VALID marking (again)

A flaw was found in the net/shaper component of the Linux kernel. A race condition exists in how VALID marks are handled for entries in an XArray. This can lead to a Use-After-Free UAF vulnerability, where memory is incorrectly freed while still in use, potentially allowing an attacker to cause a...

CVE-2026-64054

A flaw was found in the net/shaper component of the Linux kernel. This vulnerability occurs because the netshapernlgroupdoit function does not properly handle duplicate leaf entries in a GROUP request. A local attacker could exploit this by supplying the same leaf handle multiple times, leading t...
