Description OSIDB Bzimport 2025-01-06 17:01:09 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mtd: rawnand: fix double free in atmel_pmecc_create_user()

The "user" pointer was converted from being allocated with kzalloc() to
being allocated by devm_kzalloc().  Calling kfree(user) will lead to a
double free.
