  3. CVE-2023-53134
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Avoid order-5 memory allocation for TPA data The driver needs to keep track of all the possible concurrent TPA (GRO/LRO) completions on the aggregation ring. On P5 chips, the maximum number of concurrent TPA is 256 and the amount of memory we allocate is order-5 on systems using 4K pages. Memory allocation failure has been reported: NetworkManager: page allocation failure: order:5, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0-1 CPU: 15 PID: 2995 Comm: NetworkManager Kdump: loaded Not tainted 5.10.156 #1 Hardware name: Dell Inc.

This will reduce it to order-0 allocations.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bnxt_en: Evita la asignación de memoria de orden 5 para datos TPA. El controlador debe registrar todas las posibles finalizaciones simultáneas de TPA (GRO/LRO) en el anillo de agregación. En chips P5, el número máximo de TPA simultáneas es de 256 y la cantidad de memoria que asignamos es de orden 5 en sistemas que utilizan páginas de 4K. Se informó un error de asignación de memoria: NetworkManager: error de asignación de página: orden: 5, modo: 0x40dc0 (GFP_KERNEL | __GFP_COMP | __GFP_ZERO), máscara de nodo = (null), conjunto de CPU = /, mems_allowed = 0-1 CPU: 15 PID: 2995 Comm: NetworkManager Kdump: cargado No contaminado 5.10.156 # 1 Nombre del hardware: Dell Inc.

Esto reducirá las asignaciones a un orden de 0.
