| Vetor | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
linux-image versions 3.13.0 through 3.16.0
linux-image versions prior to 3.18.5
Description
The issue affects the Linux kernel, allowing local users to load arbitrary kernel modules via a bind system call for an AF ALG socket with a parenthesized module template expression in the
salg name field. This can lead to a breach of confidentiality, integrity, and availability of protected information. The exploitation can be carried out locally.Recommendations
For linux-image versions 3.13.0 through 3.16.0, update to a version prior to 3.18.5 to resolve the issue.
For linux-image versions prior to 3.18.5, update to version 3.18.5 or later to resolve the issue.
As a temporary workaround, consider restricting access to the AF ALG socket to minimize the risk of exploitation.
