Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from mishandling of errors in complex rule re-hashing in the net/mlx5 HWS component, which could lead to soft lockups...

AZL-73854 CVE-2025-38572 affecting package kernel for versions less than 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: ipv6: reject malicious packets in ipv6gsosegment syzbot was able to craft a packet with very long IPv6 extension headers leading to an overflow of skb-transportheader. This 16bit field has a limited range. Add...

CVE-2025-38572

CVE-2025-38572 affects the Linux kernel IPv6 path, where an attacker could craft IPv6 extension headers to overflow skb->transport_header via ipv6_gso_segment() when processing very long headers. The root cause is related to the 16-bit transport header field handling, with a suggested fix addi...
