CVE-2026-72181

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory management flaw exists in the MIPS scheduler when CONFIG CPUMASK OFFSTACK is enabled. In this configuration, cpumask var t is treated as a pointer, which causes sizeof(new mask) to evaluate to the pointer size rather than the actual mask size. This leads to copy from user() overwriting the mask pointer, resulting in memory corruption. Additionally, the original logic incorrectly executed copy from user() before the mask was allocated.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
