VUL-0: CVE-2018-10872: kernel-source: error in exception handling leads to DoS (CVE-2018-8897 regression)
Last modified: 2019-12-20 07:46:31 UTC
A flaw was found in the way the Linux kernel handled exceptions delivered after
a stack switch operation via Mov SS or Pop SS instructions. During the stack
switch operation, processor does not deliver interrupts and exceptions, they are
delivered once the first instruction after the stack switch is executed. An
unprivileged system user could use this flaw to crash the system kernel
resulting in DoS. This CVE-2018-10872 was assigned due to regression of
CVE-2018-8897 in Red Hat Enterprise Linux 6.10 GA kernel. No other versions are
affected by this CVE.
This seems to be a Redhat specific regression, it does not affect SUSE Linux Enterprise or openSUSE kernels.
