Description OSIDB Bzimport 2025-05-01 14:04:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btrtl: Prevent potential NULL dereference

The btrtl_initialize() function checks that rtl_load_file() either
had an error or it loaded a zero length file.  However, if it loaded
a zero length file then the error code is not set correctly.  It
results in an error pointer vs NULL bug, followed by a NULL pointer
dereference.  This was detected by Smatch:

drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to 'ERR_PTR'
