Detail
Modified After Enrichment This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.
Current Description
The IPv6 flow label handling code (ip6_flowlabel.c) in Linux kernels 2.4 up to 2.4.32 and 2.6 before 2.6.14 modifies the wrong variable in certain circumstances, which allows local users to corrupt kernel memory or cause a denial of service (crash) by triggering a free of non-allocated memory.
