Off-by-one error in the bpf_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 3.1.8, when BPF JIT is enabled, allows local users to cause a denial of service (system crash) or possibly gain privileges via a long jump after a conditional jump.

Comment 1 Marcus Meissner 2016-08-20 11:38:17 UTC 
The patch is in patches.kernel.org/patch-3.0.15-16 for our 3.0. kernels.

sles11 sp2 ltss has received this as an update.
sles11 sp3 and sp4 have it since shipment.

2.6.32 has no bpf jit compiler.

rest is fixed.
