CVE-2025-21648

CVE-2025-21648 affects the Linux kernel netfilter conntrack code. The vulnerability arises from the hashtable resize path where the maximum size could exceed practical limits, risking a WARN_ON_ONCE in __kvmalloc_node_noprof() when __GFP_NOWARN is unset. The fix clamps the conntrack hashtable siz...

In the Linux kernel, the following vulnerability has been resolved: udp: Set SOCKRCUFREE earlier in udplibgetport. syzkaller triggered the warning 0 in udpv4earlydemux. In udpv46earlydemux and sklookup, we do not touch the refcount of the looked-up sk and use sockpfree as skb-destructor, so we...

log4j1-socketappender: DoS via hashmap logging

A flaw was found in Chainsaw and SocketAppender components with Log4j 1.x on JRE, less than 1.7. This issue may allow an attacker to use a logging entry with a specially-crafted hashmap or hashtable, depending on which logging component is in use, to process and exhaust the available memory in th...
