CVE-2026-68292

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ice driver where the ice is txtime ena() function fails to verify the VSI type before checking the pf->txtime txqs bitmap. This bitmap tracks Earliest TxTime First (ETF) offload—a feature that prioritizes the transmission of packets based on a specified timestamp—and is intended only for PF VSI queues. When ETF is enabled on a PF Tx queue, a subsequent PCI reset can cause the driver to incorrectly identify a CTRL VSI ring as having ETF enabled. This leads the ice vsi cfg txq() function to erroneously allocate a tstamp ring for the CTRL VSI. Because CTRL VSI rings lack an associated netdev, the ice clean tx ring() function returns early, bypassing ice free tx tstamp ring() and resulting in a 64-byte memory leak per PCI reset.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
