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 the Linux kernel that stems from a failure to refresh the queue when reading sockets by TLS, which could lead to the use of a freed skb...

CVE-2025-38463

In the Linux kernel, the following vulnerability has been resolved: tcp: Correct signedness in skb remaining space calculation Syzkaller reported a bug 1 where sk-skforwardalloc can overflow. When we send data, if an skb exists at the tail of the write queue, the kernel will attempt to append the...
