Intel LPMD Thermal Netlink Integer Underflow Vulnerability\", \n  \"Content\": \"CVE ID : CVE-2025-21840 \nPublished : March 7, 2025, 9:15 a.m. | 1\u00a0hour, 46\u00a0minutes ago \nDescription : In the Linux kernel, the following vulnerability has been resolved:  \n  \nthermal/netlink: Prevent userspace segmentation fault by adjusting UAPI header  \n  \nThe intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITY  \nattribute to receive HFI events from kernel space, encounters a  \nsegmentation fault after commit 1773572863c4 (\"thermal: netlink: Add the  \ncommands and the events for the thresholds\").  \n  \nThe issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw value  \nwas changed while intel_lpmd still uses the old value.  \n  \nAlthough intel_lpmd can be updated to check the THERMAL_GENL_VERSION and  \nuse the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commit  \nitself is questionable.  \n  \nThe commit introduced a new element in the middle of enum thermal_genl_attr,  \nwhich affects many existing attributes and introduces potential risks  \nand unnecessary maintenance burdens for userspace thermal netlink event  \nusers.  \n  \nSolve the issue by moving the newly introduced  \nTHERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of the  \nenum thermal_genl_attr. This ensures that all existing thermal generic  \nnetlink attributes remain unaffected.  \n  \n[ rjw: Subject edits ] \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details,
