CVE-2008-3833

UnknownEPSS 0.42%

Last modified

CVE-2008-3833 is a vulnerability of currently unknown severity. The generic_file_splice_write function in fs/splice.c in the Linux kernel before 2.6.19 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory, a different vulnerability than CVE-2008-4210.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
