Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: driver core: Fix a potential null-ptr-
deref in module_add_driver() Inject fault while probing of-fpga-region, if kasprintf() fails in
module_add_driver(), the second sysfs_remove_link() in exit path will cause null-ptr-deref as below
because kernfs_name_hash() will call strlen() with NULL driver_name. Fix it by releasing resources based
on the exit path sequence. KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] Mem
