CVE-2023-53134

Estado: AnalizadaMedia (5.5)—

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:

Instead of allocating this big chunk of memory and dividing it up for the concurrent TPA instances, allocate each small chunk separately for each TPA instance. This will reduce it to order-0 allocations.
