CVE-2026-52916

The CVE-2026-52916 issue affects the Linux kernel’s BATMAN-adv fragment handling. batadv_frag_skb_buffer() is invoked when a BATADV_UNICAST_FRAG packet is received, and after defragmentation, batadv_batman_skb_recv() processes the payload again. A malicious sender could craft a BATADV_UNICAST_FRA...

Suricata 8.x < 8.0.5 Multiple Vulnerabilities

The version of OISF Suricata installed on the remote host is 8.x prior to 8.0.5. It is, therefore, affected by multiple vulnerabilities, including: - LDAP transaction state could store an unbounded number of responses. Because LDAP can be processed over UDP, crafted traffic may cause Suricata to...
