Last modified

CVE-2009-4271 is a vulnerability of currently unknown severity. The Linux kernel 2.6.9 through 2.6.17 on the x86_64 and amd64 platforms allows local users to cause a denial of service (panic) via a 32-bit application that calls mprotect on its Virtual Dynamic Shared Object (VDSO) page and then triggers a segmentation fault.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
