UnknownEPSS 0.52%

Last modified

CVE-2009-2793 is a vulnerability of currently unknown severity. The kernel in NetBSD, probably 5.0.1 and earlier, on x86 platforms does not properly handle a pre-commit failure of the iret instruction, which might allow local users to gain privileges via vectors related to a tempEIP pseudocode variable that is outside of the code-segment limits.. EPSS estimates a 0.52% chance of exploitation in the next 30 days.
