siper

Siper Escudo Siper é um firewall de lista negra IP de alto desempenho baseado em XDP, construído com Go e C eBPF. Ele permite descartar tráfego malicioso no estágio mais inicial possível da pilha de rede do Linux—no nível do driver de rede. Ao utilizar o XDP Express Data Path, o Siper processa...

SUSE CVE-2026-64352

In the Linux kernel, the following vulnerability has been resolved: bpf: Allow LPM map access from sleepable BPF programs trielookupelem annotates its rcudereferencecheck walks with only rcureadlockbhheld. Because rcudereferencecheckp, c resolves to "c || rcureadlockheld", this passes for XDP/NAP...

CVE-2026-64352

CVE-2026-64352 concerns the Linux kernel’s BPF LPM trie: sleepable BPF programs can access LPM map data due to incorrect rcu dereference checks in trie_lookup_elem/trie_update_elem/trie_delete_elem. The issue arises because trie_lookup_elem() uses rcu_dereference_check() with a condition that pas...

The vulnerability of the trie_get_next_key() function in the kernel/bpf/lpm_trie.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the triegetnextkey function in the kernel/bpf/lpmtrie.c module of the Linux operating system is related to memory allocation beyond the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of t...
