Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the PCI/P2PDMA component where the p2pmem alloc mmap() function fails to invoke percpu ref put() to release the per-CPU reference of pgmap acquired after gen pool alloc owner() when vm insert page() fails. This leads to a situation where memunmap pages() hangs indefinitely during the removal of a PCI device.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
