CVSS 7.5 · High EPSS 0,48%
Kerentanan NULL Pointer Dereference pada haproxy. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.
HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpack_dht_insert() within src/hpack-tbl.c that fails to validate the return value of hpack_dht_defrag() when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memory pressure to dereference a NULL pointer and crash HAProxy worker processes, causing denial of service.
