Description OSIDB Bzimport 2026-07-19 15:01:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix mm_struct reference leak in aie2_populate_range()

aie2_populate_range() jumps back to the again label without calling
mmput(mm), leaking a reference to the mm_struct.

Add the missing mmput() before jumping to again.
