X-Git-Tag: v2.6.20.11~17
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a9c01941701641d505c07e7364a03447c694f6e8;p=thirdparty%2Fkernel%2Fstable.git

cache_k8_northbridges() overflows beyond allocation

cache_k8_northbridges() overflows beyond allocation

cache_k8_northbridges() is storing config values to incorrect locations
(in flush_words) and also its overflowing beyond the allocation, causing
slab verification failures.
