In the Linux kernel, the following vulnerability has been resolved: Revert "thermal/drivers/hwmon: Cleanup coding style a bit" Revert commit… (CVE-2026-74604)
A use-after-free vulnerability was introduced in the Linux kernel due to a reverted commit that removed a valid check in the thermal driver subsystem. This vulnerability was fixed by reverting the problematic commit that caused the issue.
AI Analysis
Technical Summary
The Linux kernel contained a use-after-free vulnerability in the thermal driver hardware monitoring code. The vulnerability was introduced by commit 030a48b0f6ce, which cleaned up coding style but inadvertently removed a necessary check in the error path of thermal_add_hwmon_sysfs(). This removal led to a use-after-free condition. The issue was resolved by reverting the commit, restoring the valid check and eliminating the vulnerability.
Potential Impact
The vulnerability could cause use-after-free conditions in the thermal hardware monitoring subsystem of the Linux kernel, potentially leading to system instability or crashes. No specific exploitation details or impacts beyond the use-after-free condition are provided.
Mitigation Recommendations
The vulnerability has been resolved by reverting the commit that introduced the issue. Users should update to the fixed Linux kernel version that includes this revert. Patch status is confirmed as fixed by the revert; no further action is required beyond applying the updated kernel.
