1. 修复的CVE

·CVE-2022-0435

描述：Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。Linux kernel存在安全漏洞，该漏洞源于在 Linux 内核的 TIPC 协议功能中发现了堆栈溢出缺陷，用户发送带有恶意内容的数据包，其中域成员节点的数量高于允许的 64 个。如果远程用户有权访问 TIPC 网络，此漏洞允许远程用户使系统崩溃或可能提升他们的权限。

·CVE-2022-0487

描述：Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。Linux kernel 存在资源管理错误漏洞，该漏洞源于在Linux内核memstick的drivers/memstick/host/rtsx_usb_ms.c中的rtsx_usb_ms_drv_remove中发现了一个use-after-free漏洞。 在此漏洞中，具有用户权限的本地攻击者可能会影响系统机密性。

·CVE-2022-24448

描述：Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。KVM是其中的一个基于内核的虚拟机。Linux kernel 存在安全漏洞，该漏洞源于Linux 内核中的 fs/nfs/dir.c 中发现了一个问题。 如果应用程序设置了 O_DIRECTORY 标志，并尝试打开常规文件，nfs_atomic_open() 将执行常规查找。 如果找到常规文件，则应该发生 ENOTDIR，但服务器会在文件描述符中返回未初始化的数据。

·CVE-2022-24958

描述：Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。Linux kernel 中存在代码问题漏洞，该漏洞源于产品/usb/gadget/legacy/inode.c文件中对dev-＞buf的处理存在错误。以下产品及版本受到影响：Linux kernel  5.16.8 版本及之前版本。

·CVE-2022-24959

描述：Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。Linux kernel 中存在缓冲区错误漏洞，该漏洞源于产品/net/hamradio/yam.c文件中的yam_siocdevprivate函数未对内存边界做有效限制。攻击者可通过该漏洞导致缓冲区溢出。以下产品及版本受到影响：Linux kernel 5.16.5 之前版本。
