https://bugzilla.suse.com/show_bug.cgi?id=1230065 Bug ID: 1230065 Summary: fsconfig(FSCONFIG_SET_STRING) accepts invalid key string on bcachefs Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel:Filesystems Assignee: kernel-fs@suse.de Reporter: martin.doucha@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- LTP test fsconfig03 (CVE 2022-0185) fails on Tumbleweed KOTD. The test tries to overflow the filesystem parameter buffer by repeatedly setting empty key to non-empty value using fsconfig(FSCONFIG_SET_STRING). These fsconfig() calls are supposed to fail. However, bcachefs accepts them anyway at least since Tumbleweed KOTD build 6.11.0-rc3-2.g00af0c0-default. https://openqa.opensuse.org/tests/4402207#step/cve-2022-0185/8 Latest failure: https://openqa.opensuse.org/tests/4447854#step/cve-2022-0185/8 dmesg log: https://openqa.opensuse.org/tests/4447854/logfile?filename=serial0.txt Last good: 6.10.1-1.g4c78d6f-default KOTD builds between 6.10.1-1.g4c78d6f-default and 6.11.0-rc3-2.g00af0c0-default were not tested due to mkfs issue. -- You are receiving this mail because: You are on the CC list for the bug.
