UnknownEPSS 2.92%

Last modified

CVE-2006-1856 is a vulnerability of currently unknown severity. Certain modifications to the Linux kernel 2.6.16 and earlier do not add the appropriate Linux Security Modules (LSM) file_permission hooks to the (1) readv and (2) writev functions, which might allow attackers to bypass intended access restrictions.. EPSS estimates a 2.92% chance of exploitation in the next 30 days.
