Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: iio: adc: at91-sama5d2_adc: Fix potential use-after-free in sama5d2_adc driver… (CVE-2025-71199)
A use-after-free vulnerability was identified and fixed in the Linux kernel's at91-sama5d2_adc driver. The flaw occurs when scheduled work referencing a device structure is executed after the device has been freed during module removal, potentially leading to use of freed memory. This issue was resolved by ensuring that scheduled work is canceled before device cleanup proceeds. The vulnerability affects certain Linux kernel versions prior to 5.15.0-1105.112~20.04.1 and related builds. A patch is available and included in updated Linux kernel packages. Users should update and reboot to apply the fix.
AI Analysis
Technical Summary
The Linux kernel's at91-sama5d2_adc driver contained a use-after-free vulnerability (CVE-2025-71199) caused by a race condition between scheduled work execution and device removal. Specifically, the at91_adc_interrupt function schedules work that uses the indio_dev device structure, but during module removal, the device is freed asynchronously after iio_device_unregister is called. This can lead to the scheduled work accessing freed memory, causing a use-after-free condition. The fix involves canceling the scheduled work before proceeding with device cleanup in the at91_adc_remove function. This vulnerability affects multiple Linux kernel versions in the 5.15 series prior to specific patched versions for Ubuntu 20.04 LTS and 22.04 LTS. The vendor has released updated kernel packages that address this and other vulnerabilities.
Potential Impact
If exploited, this use-after-free vulnerability could lead to system instability or potential privilege escalation by causing kernel memory corruption. However, no known exploits are reported in the wild. The vulnerability affects the Linux kernel on affected versions, potentially compromising system reliability and security if unpatched.
Mitigation Recommendations
A fix is available and has been incorporated into updated Linux kernel packages for affected Ubuntu releases. Users should apply the relevant kernel updates and reboot their systems to ensure the vulnerability is remediated. Due to an ABI change in the kernel updates, recompilation and reinstallation of third-party kernel modules may be required. Follow vendor instructions for updating and rebuilding kernel modules as necessary.
