[oss-security] CVE request: Another Linux syscall auditing bug

On a 32-bit x86 kernel with syscall auditing enabled, syscall1000 will cause an OOPS. This problem goes at least as far back as Linux 3.11 and appears to be present in Linux 3.15 as well. I suspect that this bug is very old. In order to see this bug, you'll need syscall auditing on auditctl -e 1...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 2.6.33 Description: The issue is related to the do follow link function in fs/namei.c, which does not properly handle the last pathname component during use of certain filesystems. This allows local users to cau...

[oss-security] CVE request: Linux kernel DoS with syscall auditing

Issuing a system call with a random large number will OOPS, depending on configuration. A configuration that will enable this bug is: auditctl -a exit,always -S open No privilege whatsoever is required to trigger the OOPS. It's possible that this can be extended to more than just a DoS -- with so...
