AI-suggested
An official patch is available and should be applied to affected Linux kernel versions. The fix involves synchronizing interrupts to prevent the race condition in buffer mode handling. Users should update to the patched kernel versions as provided by their Linux distribution vendors. No additional mitigation actions are specified or required beyond applying the official fix.
Description
A use-after-free vulnerability in the Linux kernel's fxls8962af accelerometer driver was fixed. The flaw occurs in the fxls8962af_fifo_flush function, which uses active scan mask data without ensuring the device remains in buffer mode, leading to a race condition and potential kernel NULL pointer dereference. This vulnerability affects multiple specific Linux kernel versions and has a CVSS score of 7.8. A patch is available to address the issue by synchronizing interrupts to prevent concurrent access during buffer mode changes.
