CVE-2024-34777

CVE-2024-34777 affects the Linux kernel DMA mapping benchmark path. The issue occurs in the map_benchmark_ioctl() flow when validating node ids; node_possible() can receive an argument outside the valid [0, MAX_NUMNODES-1] range, enabling a KASAN wild-memory-access read in map_benchmark_ioctl (ke...

CVE-2024-39277 dma-mapping: benchmark: handle NUMA_NO_NODE correctly

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: benchmark: handle NUMANONODE correctly cpumaskofnode can be called for NUMANONODE inside domapbenchmark resulting in the following sanitizer report: UBSAN: array-index-out-of-bounds in...

CVE-2024-39277

In CVE-2024-39277, the Linux kernel vulnerability arises when dma-mapping benchmark bound to NUMA_NO_NODE triggers UBSAN array-index-out-of-bounds in arch/x86/topology.h. The root cause is calling cpumask_of_node() for NUMA_NO_NODE inside do_map_benchmark(), leading to an invalid cpumask[-1] acce...
