| Vector | AV: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 a flaw in the
ice ll ts intr() function related to handling Tx timestamps from the E810 firmware. The function does not verify if the tracker is initialized before accessing it, leading to potential NULL dereference or use-after-free issues. This occurs because the function accesses the tx->in use bitmap without checking if the tracker is initialized. The fix involves checking if the tracker is initialized before accessing its fields, ensuring that the in use bitmap and other fields are only accessed when the tracker is valid.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
