CVE-2024-57938: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-57938 is a vulnerability discovered in the Linux kernel's SCTP (Stream Control Transmission Protocol) implementation. The issue was identified in the sctpassociationinit() function where an integer overflow could occur when setting the autoclose timer. While by default maxautoclose equals to INTMAX / HZ, users can set net.sctp.maxautoclose to UINTMAX, which could trigger the overflow condition (NVD).

The vulnerability is classified as an Integer Overflow or Wraparound (CWE-190) with a CVSS v3.1 Base Score of 5.5 (Medium) and vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The issue specifically occurs in the sctpassociationinit() function where the autoclose timer value is calculated without proper type casting, potentially leading to an integer overflow when multiplying sp->autoclose with HZ (NVD).

The vulnerability affects multiple versions of the Linux kernel, including versions from 3.13 up to (excluding) 5.4.289, 5.5 to 5.10.233, 5.11 to 5.15.176, 5.16 to 6.1.124, 6.2 to 6.6.70, and 6.7 to 6.12.9, as well as several release candidates of version 6.13 (NVD).

A fix has been implemented by modifying the calculation of the autoclose timer value in the sctpassociationinit() function. The patch adds proper type casting to (unsigned long) before performing the multiplication with HZ to prevent the integer overflow (Kernel Patch).
