Bug ID: 603
Summary: The variable
drivers/regex/octeontx2/otx2_regexdev.c:pci_id_ree_tab le is not initialized, which will cause the global variable to overflow, which is a security risk.
Product: DPDK
Version: 20.08
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
pci_id_ree_table needs to be initialized as:
static struct rte_pci_id pci_id_ree_table[] = {
{ RTE_PCI_DEVICE(PCI_VENDOR_ID_CAVIUM, PCI_DEVID_OCTEONTX2_RVU_REE_PF) } ,
{ .vendor_id = 0, /* sentinel */ }
,
};
Test steps:
1. Compile add option -Db_sanitize=address
CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dbuildtype=debug -Db_sanitize=address --default-library=static x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc -j 55
2. start dpdp-testpmd ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c 0x6 -n 4 – -i
3. a global-buffer-overflow
