CVE-2007-2453

UnknownEPSS 0.38%

Last modified

CVE-2007-2453 is a vulnerability of currently unknown severity. The random number feature in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, (1) does not properly seed pools when there is no entropy, or (2) uses an incorrect cast when extracting entropy, which might cause the random number generator to provide the same values after reboots on systems without an entropy source.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
