Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition exists in the Linux kernel for powerpc/64s architectures during the unmapping of Page Middle Directory (PMD) migration entries. The issue occurs when a
move pages() system call is executed on a PMD Transparent Huge Page (THP) simultaneously with an munmap() operation. Specifically, a race window opens during the page copy phase where a PMD entry may act as a migration swap entry. If munmap() is called at this time, it can trigger a kernel BUG in the pmdp huge get and clear full() function because the expected PMD present state is not met.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
