Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.14.0-rc2+
Description
A divide by zero error occurs in the Linux kernel when calculating the journal watermark in Inline mode, as the journal is unused and journal sectors is zero. This can cause a system crash when a simple table query, such as
dmsetup table, is executed. The issue is reliably reproducible on certain systems, including 32-bit testing machines.Recommendations
For Linux kernel versions prior to 6.14.0-rc2+, update to a version that includes the fix for the divide by zero error in Inline mode.
As a temporary workaround, consider avoiding the use of
dmsetup table on affected systems until a patch is available.Exploit
