Hello, Linux kernel kernel's Memory Management Unit(MMU) is vulnerable to a crash caused by unlocked memory pages. It could occur during the memory page migration or while cleaning the swap cache pages. An unprivileged user/program could use this flaw to crash the system kernel, resulting in DoS. Upstream fix: ------------- -> https://git.kernel.org/linus/57e68e9cd65b4b8eb4045a1e0d0746458502554c Introduced in: -------------- -> https://git.kernel.org/linus/b291f000393f5a0b679012b39d79fbc85c018233 Thank you. -- Prasad J Pandit / Red Hat Security Response Team
