CVE-2025-38359

Name of the Vulnerable Software and Affected Versions Linux Kernel versions 6.16.0-20250531.rc0.git0.69b3a602feac.63.fc42.s390x+debug and earlier.

Description A flaw exists in the Linux kernel related to handling in atomic() within the do secure storage access() function. User space accesses to non-exported pages in atomic context can lead to incorrect page fault resolution, potentially resulting in a kernel bug. Debug options may reveal call traces indicating a sleeping function being called from an invalid context. The issue arises because taking the mmap lock is not permitted while in atomic context.

Recommendations Update to a newer version of the Linux Kernel to address this issue.
