07 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]() The ACPI buffer memory (out.pointer) returned by wmi_evaluate_method() is not freed after the call, so it leads to memory leak. The method results in ACPI buffer is not used, so just pass NULL to wmi_evaluate_method() which fixes the memory leak.

07 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure If creation or finalization of a checkpoint fails due to anomalies in the checkpoint metadata on disk, a kernel warning is generated. This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted with panic_on_warn, does not panic. A nilfs_error is appropriate here to handle the abnormal filesystem condition.
