Description

1) Input validation error (CVE-ID: CVE-2011-1019)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The dev_load function in net/core/dev.c in the Linux kernel before 2.6.38 allows local users to bypass an intended CAP_SYS_MODULE capability requirement and load arbitrary modules by leveraging the CAP_NET_ADMIN capability.
