AI-suggested
A fix for this memory leak vulnerability has been implemented in the affected Linux kernel versions. Users should apply the official patches or update to fixed kernel versions to remediate this issue. No additional mitigation steps are indicated.
Description
A memory leak vulnerability exists in the Linux kernel's gpiolib subsystem within the function gpiod_set_array_value_complex(). The issue occurs on error paths when a call to gpiochip_set_multiple() fails, causing an early return that bypasses freeing allocated bitmaps. This flaw can lead to memory being leaked during these error conditions. The vulnerability affects specific versions of the Linux kernel and has been addressed by deferring the return code check until after the bitmap free operation.
