CVE-2026-100236— Dpdk: dpdk: heap out-of-bounds read/write in gso header copy
Quick assessment
Affected
Red Hat Fast Datapath for RHEL 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
发现 DPDK GSO 库中存在一个漏洞。在使用软件 GSO 将数据包头拷贝到新的 mbuf 时，系统未检查该头部是否足以容纳在源数据包的第一个分段中或目标缓冲区中。若头部长度大于配置的 GSO 分段大小，可能导致载荷大小计算发生下溢。处理使用软件 GSO 的远程或访客提供的数据包时，可能触发越界读或越界写操作。

Vulnerability Title
Dpdk: dpdk: heap out-of-bounds read/write in gso header copy
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write.
