A flaw was found in the Linux kernel's network traffic control subsystem. A local user can exploit this vulnerability to cause an information disclosure of kernel stack data. When dumping text search filter configurations, the kernel fails to initialize a stack structure before copying it into user-space response messages. A local user can query these filter details to view uninitialized kernel memory, potentially exposing sensitive system data.
