CVE-2021-47312

The CVE-2021-47312 issue in Linux kernel nf_tables caused a NULL pointer dereference during error handling when flow is NULL (chain flags NFT_CHAIN_HW_OFFLOAD is false). The fix ensures nft_flow_rule_destroy is only called if flow is non-null, preventing the crash in the error path. Connected ven...

CVE-2021-47265

CVE-2021-47265 is a Linux kernel RDMA issue in the mlx5_ib driver. The vulnerability stems from missing validation of the user-supplied port when creating a flow rule, leading to an improper check and a kernel oops as shown in the call trace (_create_flow_rule … mlx5_ib_create_flow …). The CVE ha...
