CVE-2026-23379

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.19.0-virtme #45

Description The Linux kernel contained a flaw in the ETS scheduler offload path where averaging over the sums of quanta could lead to an integer overflow and subsequent division by zero. This could trigger a kernel panic, potentially disrupting system operation. The issue stemmed from using unsigned integers of the same size as the individual DRR quanta for calculations involving 'q sum' and 'q psum'.

Recommendations Update to a newer version of the Linux kernel that addresses this issue.
