CVE-2011-2707: Linux Kernel

Medium severity, CVSS 6.0. EPSS: 0.4% chance of exploitation in the next 30 days.

The ptrace_setxregs function in arch/xtensa/kernel/ptrace.c in the Linux kernel before 3.1 does not validate user-space pointers, which allows local users to obtain sensitive information from kernel memory locations via a crafted PTRACE_SETXTREGS request.

Affected products

• Linux Linux Kernel: before 3.1 (fixed in 3.1)
