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 originates in the net, sunrpc module in the xstcpsetupsocket, where the BPF program may return -EPERM if the connection...

The vulnerability of the may_update_sockmap() function in the BPF subsystem of the Linux operating system allows a attacker to compromise the integrity of the protected information.

The vulnerability of the mayupdatesockmap function in the kernel/bpf/verifier.c module of the BPF subsystem of the Linux operating system is related to insufficient privilege checks. Exploiting this vulnerability could allow an attacker to compromise the integrity of protected information...
