CVE-2011-1180 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Multiple stack-based buffer overflows in the iriap_getvaluebyclass_indication function in net/irda/iriap.c in the Linux kernel before 2.6.39 allow remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging connectivity to an IrDA infrared network and sending a large integer value for a (1) name length or (2) attribute length.. EPSS estimates a 2.98% chance of exploitation in the next 30 days.
