- Summary
- [none]
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics-rmi4 - fix use after free in rmiunregisterfunction()
The putdevice() calls rmireleasefunction() which frees "fn" so the dereference on the next line "fn->numofirqs" is a use after free. Move the putdevice() to the end to fix this.
