CVE-2009-1046: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: version 2.6.25 only; version 2.6.28 only; version 2.6.28.1 only; version 2.6.28.2 only; version 2.6.28.3 only
