Description |
The Linux kernel contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered because of a race condition in the Linux netfilter code. The 'do_add_counters()' function in 'net/ipv4/netfilter/arp_tables.c' and 'net/ipv6/netfilter/arp_tables.c' lacks a check for a parameter that might allow 'IPT_ENTRY_ITERATE()' to read beyond its intended boundaries, potentially accessing sensitive kernel memory and hence resulting in a loss of confidentiality. |
