The vulnerability of the gup_pud_range() function in the mm/gup.c module of the Linux kernel’s memory management subsystem allows a hacker to cause a service failure.

The vulnerability of the guppudrange function in the mm/gup.c module of the Linux kernel’s memory management subsystem is related to resource management errors. Exploiting this vulnerability could allow an attacker to cause a system failure...

CVE-2022-48986

In the Linux kernel, the following vulnerability has been resolved: mm/gup: fix guppudrange for dax For dax pud, pudhuge returns true on x86. So the function works as long as hugetlb is configured. However, dax doesn't depend on hugetlb. Commit 414fd080d125 "mm/gup: fix guppmdrange for dax" fixed...

CVE-2022-48986

CVE-2022-48986 targets the Linux kernel memory management path for dax. The issue arises because pud_huge() returns true on x86 for dax puds, allowing the gup_pud_range path to behave unexpectedly when hugetlb is not in use, which can trigger a general protection fault and kernel panic in get_use...
