CVE-2025-38617
CVSS v3.1
4.7
| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A race condition exists in the
packet set ring() and packet notifier() functions within the net/packet module. This occurs when packet set ring() releases po->bind lock, allowing another thread to execute packet notifier() and process an NETDEV UP event concurrently. This issue is similar to a previously resolved race condition addressed in commit 15fe076edea7. The fix involves temporarily setting po->num to zero to prevent socket unhooking until the lock is reacquired.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
