Last modified

CVE-2009-1046 is a vulnerability of currently unknown severity. The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an "off-by-two memory error." NOTE: it is not clear whether this issue crosses privilege boundaries.. EPSS estimates a 0.78% chance of exploitation in the next 30 days.
