MEDIUMCVSS Vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Lifecycle Timeline
3Description
In the Linux kernel, the following vulnerability has been resolved: rdma/cxgb4: Prevent potential integer overflow on 32bit The "gl->tot_len" variable is controlled by the user. It comes from process_responses(). On 32bit systems, the "gl->tot_len + sizeof(struct cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an integer wrapping bug. Use size_add() to prevent this.
Analysis
In the Linux kernel, the following vulnerability has been resolved: rdma/cxgb4: Prevent potential integer overflow on 32bit The "gl->tot_len" variable is controlled by the user. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Technical Context
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. In the Linux kernel, the following vulnerability has been resolved: rdma/cxgb4: Prevent potential integer overflow on 32bit The "gl->tot_len" variable is controlled by the user. It comes from process_responses(). On 32bit systems, the "gl->tot_len + sizeof(struct cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an integer wrapping bug. Use size_add() to prevent this. Affected products include: Linux Linux Kernel.
Affected Products
