CVE-2011-1493 is a vulnerability of currently unknown severity. Array index error in the rose_parse_national function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by composing FAC_NATIONAL_DIGIS data that specifies a large number of digipeaters, and then sending this data to a ROSE socket.. EPSS estimates a 3.36% chance of exploitation in the next 30 days.
