Null pointer dereference

The vmsplicetouser function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which might allow local users to access arbitrary kernel memory locations...

CVE-2008-0010

CVE-2008-0010 concerns the Linux kernel vulnerability in copy_from_user_mmap_sem (fs/splice.c) affecting kernels 2.6.22 through 2.6.24. The root cause is a failure to validate a userspace pointer before dereferencing, which allows a local attacker to read from arbitrary kernel memory locations. A...

Linux Kernel IPv6 Hop-By-Hop头字段远程拒绝服务漏洞

Linux是一款开放源代码的操作系统。 Linux内核处理特定构建的IPv6 'Hop-By-Hop'头字段数据存在问题，远程攻击者可以利用漏洞对系统进行拒绝服务攻击。 由于skb-dst在ip6routeinput中分配，不正确在hop-by-hop选项处理器中使用，可导致造成内核出现问题，造成拒绝服务攻击。 Ubuntu Ubuntu Linux 7.10 sparc Ubuntu Ubuntu Linux 7.10 powerpc Ubuntu Ubuntu Linux 7.10 i386 Ubuntu Ubuntu Linux 7.10 amd64 Ubuntu Ubuntu...

Linux Kernel 2.6.22 - IPv6 Hop-By-Hop Header Remote Denial of Service

Linux Kernel 2.6.22 - IPv6 Hop-By-Hop Header Remote Denial of Service / source: https://www.securityfocus.com/bid/26943/info The Linux kernel is prone to a remote denial-of-service vulnerability because it fails to adequately validate specially crafted IPv6 'Hop-By-Hop' headers. Attackers can...

Linux Kernel 2.6.22 - IPv6 Hop-By-Hop Header Remote Denial of Service

/ source: https://www.securityfocus.com/bid/26943/info The Linux kernel is prone to a remote denial-of-service vulnerability because it fails to adequately validate specially crafted IPv6 'Hop-By-Hop' headers.
