Linux内核 Keyrings 引用计数溢出 UAF 漏洞

漏洞分析 Linux Kernel的这个漏洞会造成两个影响，第一个是造成信息泄露，可以bypass ASLR，另一个是UAF造成代码执行，利用的是KeyRing机制中的两个漏洞，一个是对Keyring操作控制不严谨，另一个是利用对Keyring计数变量控制不严谨，其中代码执行利用条件相对苛刻，下面对此漏洞进行详细分析。 Keyring信息泄露： Keyring和安全密钥有关，进程可以申请自己新的keyring，同时也可以通过申请新的keyring替换老的keyring，其中，调用到joinsessionkeyring函数。 long joinsessionkeyringconst cha...
