CVE-2026-72064

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

Description An issue exists in the MANA driver where RX buffers are allocated from page pool fragments when the frag count is greater than 1. In these instances, buffers remain DMA mapped by the page pool, and the RX completion path fails to call the dma unmap single() function. Consequently, the implicit sync-for-CPU operation usually performed by dma unmap single() is missing before packet data is passed to the networking stack. This results in RX failure on configurations requiring explicit DMA syncing, such as those booted with swiotlb=force.

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