Description

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.

Affected configurations

• linux linux kernel 2.6.0 • linux linux kernel 2.6.1 • linux linux kernel 2.6.2 • linux linux kernel 2.6.3 • linux linux kernel 2.6.4 • linux linux kernel 2.6.5 • linux linux kernel 2.6.6 • linux linux kernel 2.6.7 • linux linux kernel 2.6.8 • linux linux kernel 2.6.9 • linux linux kernel 2.6.10 • linux linux kernel 2.6.11 • linux linux kernel 2.6.11.1 • linux linux kernel 2.6.11.2 • linux linux kernel 2.6.11.3 • linux linux kernel 2.6.11.4 • linux linux kernel 2.6.11.5 • linux linux kernel 2.6.11.6 • linux linux kernel 2.6.11.7 • linux linux kernel 2.6.11.8 • linux linux kernel 2.6.11.9 • linux linux kernel 2.6.11.10 • linux linux kernel 2.6.11.11 • linux linux kernel 2.6.11.12 • linux linux kernel 2.6.12 • linux linux kernel 2.6.12.1 • linux linux kernel 2.6.12.2 • linux linux kernel 2.6.12.3 • linux linux kernel 2.6.12.4 • linux linux kernel 2.6.12.5 • linux linux kernel 2.6.12.6 • linux linux kernel 2.6.13 • linux linux kernel 2.6.13.1 • linux linux kernel 2.6.13.2 • linux linux kernel 2.6.13.3 • linux linux kernel 2.6.13.4 • linux linux kernel 2.6.14 • linux linux kernel 2.6.14.1 • linux linux kernel 2.6.14.2 • linux linux kernel 2.6.14.3 • linux linux kernel 2.6.14.4 • linux linux kernel 2.6.14.5 • linux linux kernel 2.6.14.6 • linux linux kernel 2.6.14.7 • linux linux kernel 2.6.15 • linux linux kernel 2.6.15.1 • linux linux kernel 2.6.15.2 • linux linux kernel 2.6.15.3 • linux linux kernel 2.6.15.4 • linux linux kernel 2.6.15.5 • linux linux kernel 2.6.15.6 • linux linux kernel 2.6.15.7 • linux linux kernel 2.6.16 • linux linux kernel 2.6.16.1 • linux linux kernel 2.6.16.2 • linux linux kernel 2.6.16.3 • linux linux kernel 2.6.16.4 • linux linux kernel 2.6.16 rc7 • linux linux kernel 2.6 test9 cvs
