| Vector | AV:L/AC:L/PR:N/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:
The issue is related to the ks8851 component in the Linux kernel, which is associated with incorrect resource locking. This can lead to a denial of service. The problem arises when the
net rx action() function triggers the .start xmit callback, protected by the same lock as the IRQ handler, potentially causing a hang due to attempting to claim an already claimed lock. The solution involves removing the BH manipulation and queuing received packets in the IRQ handler before pushing them into netif rx() outside the lock-protected critical section.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
