Last modified

CVE-2006-0744 is a vulnerability of currently unknown severity. Linux kernel before 2.6.16.5 does not properly handle uncanonical return addresses on Intel EM64T CPUs, which reports an exception in the SYSRET instead of the next instruction, which causes the kernel exception handler to run on the user stack with the wrong GS.. EPSS estimates a 0.46% chance of exploitation in the next 30 days.

Description
