Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a memory leak vulnerability that originates from nft_set_catchall_flush in net/netfilter/nf_tables_api.c not freeing or failing to free dynamically allocated heap memory, which can be exploited by an attacker to cause an information leak.
