CVE-2011-4080

The sysrqsysctlhandler function in kernel/sysctl.c in the Linux kernel before 2.6.39 does not require the CAPSYSADMIN capability to modify the dmesgrestrict value, which allows local users to bypass intended access restrictions and read the kernel ring buffer by leveraging root privileges, as...

CVE-2011-4080

CVE-2011-4080 affects the Linux kernel: sysrq_sysctl_handler in kernel/sysctl.c did not require CAP_SYS_ADMIN to modify dmesg_restrict, enabling local users (e.g., in LXC) to bypass restrictions and read the kernel ring buffer with root privileges. Public sources (Red Hat, SUSE, NVD) cite impact ...
