CVE-2025-23163: In the Linux kernel, the following vulnerability has been resolved: net: vlan: don't propagate flags on open With the

A deadlock (a situation where the system gets stuck because two parts of code are waiting for each other) was discovered in the Linux kernel's VLAN (virtual LAN, a way to create multiple logical networks on one physical device) handling code. The problem occurred when virtual network devices tried to acquire the same lock twice during network interface initialization, causing the system to hang. The fix changes when certain network flags are propagated, moving them from the device open process to the flag change process instead.
