CVE-2025-38730

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains an issue where ring provided buffers in the networking context, specifically when MSG WAITALL is set or with streaming sockets, can be incorrectly retained across retries. This can lead to the use of invalid or shared memory, potentially resulting in data corruption in applications if multiple sockets utilize the same buffer group. The issue arises from failing to recycle or commit buffers on retry, leading to potential access of unallocated memory if the buffer ring is unregistered or shared between receives.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
