Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已被修复： 模块（module）：修复 codetag_load_module() 丢失错误码的问题 如果 codetag_load_module() 调用失败，错误码变量 err 不会被设置为反映该失败，导致 load_module() 在模块已被卸载后仍返回 0。 此外，如果该模块是一个实时补丁（livepatch），则 copy_module_elf() 所分配的 mod->klp_info 内存会在该错误路径上发生泄漏。现已通过新增的 livepatch_cleanup 标签
