CVE-2025-24947 (GCVE-0-2025-24947)

Vulnerability from nvd – Published: 2025-02-20 00:00 – Updated: 2025-02-20 20:19
VLAI?
Summary
A hash collision vulnerability (in the hash table used to manage connections) in LSQUIC (aka LiteSpeed QUIC) before 4.2.0 allows remote attackers to cause a considerable CPU load on the server (a Hash DoS attack) by initiating connections with colliding Source Connection IDs (SCIDs). This is caused by XXH32 usage.
Severity ?
5.3 (Medium)

CVE-2025-24947 (GCVE-0-2025-24947)

Vulnerability from cvelistv5 – Published: 2025-02-20 00:00 – Updated: 2025-02-20 20:19
VLAI?
Summary
A hash collision vulnerability (in the hash table used to manage connections) in LSQUIC (aka LiteSpeed QUIC) before 4.2.0 allows remote attackers to cause a considerable CPU load on the server (a Hash DoS attack) by initiating connections with colliding Source Connection IDs (SCIDs). This is caused by XXH32 usage.
Severity ?
