In affected libpcap versions during the setup of a remote packet capture the internal function sockinitaddress calls getaddrinfo and possibly freeaddrinfo, but does not clearly indicate to the caller function whether freeaddrinfo still remains to be called after the function returns. This makes i...

CVE-2026-33630

A flaw was found in c-ares. A use-after-free / double-free vulnerability exists in the query-completion handling path, where a query callback is invoked while the query is still linked in internal lookup structures. A remote attacker can exploit this via aresgetaddrinfo over TCP by sending crafte...

PT-2026-56309

Name of the Vulnerable Software and Affected Versions c-ares versions prior to 1.34.7 Description The software contains multiple issues. A use-after-free or double-free condition exists in query-completion handling, which can be remotely triggered via the ares getaddrinfo function over TCP...

CVE-2026-14607

A weakness has been identified in RT-Thread up to 5.0.2. This affects the function sysgetaddrinfo of the file components/lwp/lwpsyscall.c. Executing a manipulation of the argument aiaddr can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to...

Name of the Vulnerable Software and Affected Versions RT-Thread versions prior to 5.0.3 Description A memory corruption issue exists in the sys getaddrinfo function within the components/lwp/lwp syscall.c file. A local attacker can trigger this by manipulating the ai addr argument. Recommendation...

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo() (subsys/net/lib/sockets/getaddrinfo.c) has a use-after-return risk from a stack-allocated ai_state being kept as user_data during a DNS resolver retry. If a semaphore wait times out and the code retries without cancelling the previous query or resetting the sema...
