UnknownEPSS 2.43%

Last modified

CVE-2004-0077 is a vulnerability of currently unknown severity. The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different vulnerability than CAN-2003-0985.. EPSS estimates a 2.43% chance of exploitation in the next 30 days.
