Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the nftchainvalidate function potentially entering a recursive loop, which may lead to a CPU soft...

The vulnerability of the nft_chain_lookup_byid() function in the net/netfilter/nf_tables_api.c module of the netfilter component of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the nftchainlookupbyid function in the net/netfilter/nftablesapi.c module of the netfilter component of the Linux operating system is related to the use of a previously released resource. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

The vulnerability of the nft_netdev_event() function in the net/netfilter/nft_chain_filter.c module of the netfilter component of the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the nftnetdevevent function in the net/netfilter/nftchainfilter.c module of the netfilter component of the Linux operating system is related to improper control of resource identifiers “resource injection”. Exploiting this vulnerability could allow a attacker to cause service...
