Description
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to resource management error within the mark_mt() and mark_mt_init() functions in net/netfilter/xt_mark.c, within the sizeof() function in net/netfilter/xt_connmark.c, within the connlimit_mt_destroy() function in net/netfilter/xt_connlimit.c, within the connbytes_mt_check() function in net/netfilter/xt_connbytes.c, within the xt_cluster_mt_destroy() function in net/netfilter/xt_cluster.c, within the sizeof() function in net/netfilter/xt_addrtype.c, within the trace_tg() function in net/netfilter/xt_TRACE.c, within the offsetof() function in net/netfilter/xt_SECMARK.c, within the xt_rateest_tg_destroy() and xt_rateest_tg_init() functions in net/netfilter/xt_RATEEST.c, within the nflog_tg_destroy() function in net/netfilter/xt_NFLOG.c, within the led_tg_destroy() function in net/netfilter/xt_LED.c, within the idletimer_tg_destroy_v1() function in net/netfilter/xt_IDLETIMER.c, within the xt_ct_tg_destroy_v1() and sizeof() functions in net/netfilter/xt_CT.c, within the connsecmark_tg_destroy() function in net/netfilter/xt_CONNSECMARK.c, within the sizeof() function in net/netfilter/xt_CLASSIFY.c, within the checksum_tg_check() function in net/netfilter/xt_CHECKSUM.c. A local user can perform a denial of service (DoS) attack.
