CVE-2024-49571
CVSS v2.0
6.2
Medium
| Vector | AV:A/AC:L/Au:S/C:P/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.74
Description
The issue concerns the Linux kernel, specifically the net/smc component. When receiving a proposal message in the server, the fields
iparea offset and ipv6 prefixes cnt from the remote client are not fully trusted. If the iparea offset exceeds its maximum value, it may lead to accessing the wrong address, potentially causing a crash. The patch addresses this by checking iparea offset and ipv6 prefixes cnt before using them.Recommendations
For versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider restricting access to the net/smc component until the patch is applied.
