VUL-0: CVE-2018-18397: kernel-source: kernel: userfaultfd bypasses tmpfs file permissions
Last modified: 2022-03-04 21:05:58 UTC
rh#1641548 A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behaviour. At this time there is an understanding there is no crash or priviledge escalation but the impact of modifications on these filesystems of files in production systems may have adverse affects. Upstream patch: https://lore.kernel.org/lkml/20181126173452.26955-1-aarcange@redhat.com/T/#u References: https://bugzilla.redhat.com/show_bug.cgi?id=1641548 http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-18397 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-18397
seems to be 4.11+ ?
(In reply to Marcus Meissner from comment #1) > seems to be 4.11+ ? Judging from Fixes tag, yes, it looks so --> SLE15+. Not sure who are responsible for these. Maybe mm guys would like to take?
