CVE-2006-1856

High
Published: Translated: NVD NIST

Summary

In Linux kernels 2.6.16 and earlier, the readv and writev functions lack the appropriate LSM (Linux Security Modules) file_permission hooks, potentially allowing bypass of intended access restrictions.

Risk Assessment

Attackers could exploit this vulnerability to gain unauthorized access to files or data, circumventing access control mechanisms defined by security modules.

Recommendation

Immediately update the Linux kernel to a version later than 2.6.16, which includes the fix adding the missing LSM hooks.
