CVE-2026-99226
The Linux kernel contains a vulnerability in the named keyring lookup function find_keyring_by_name(). The root cause is a use-after-free (confirmed by KASAN reports) where the function reads keyring->user->uid while holding keyring_name_lock. Because this lock only protects the keyring's n...

SUSE CVE-2010-1437
Race condition in the findkeyringbyname function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service memory corruption and system crash or possibly have unspecified other impact via keyctl session commands that trigger access to a...
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...
