CVE-2026-68185

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Move jump_label_init() before parse_early_param()

When enabling both CONFIG_MEM_ALLOC_PROFILING=y and

CONFIG_MEM_ALLOC_PROFILING_ENABLED_BY_DEFAULT=y, then diabling memory

profiling by adding the boot parameter 'sysctl.vm.mem_profiling=0' will

cause the kernel failed to boot.

After analysis, this is because jump_label_init() must be called before

parse_early_param(), the early param handlers may modify static keys by

static_branch_enable/disable().

Fix this by moving jump_label_init() to before parse_early_param(). The

solution is similar to other architectures.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
