--- title: "CVE-2010-3301\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2010-3301?format=md keywords: index, follow --- # CVE-2010-3301 Publication date 15 September 2010 Last updated 24 July 2024 --- Ubuntu priority **High** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86\_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression. ### From the Ubuntu Security Team Ben Hawkes discovered that the Linux kernel did not correctly filter registers on 64bit kernels when performing 32bit system calls. On a 64bit system, a local attacker could manipulate 32bit system calls to gain root privileges.
