Subject: [PATCH 33/49] drivers/usb/class/cdc-acm.c: clear dangling pointer
|
|
|
|
commit e7c8e8605d0bafc705ff27f9da98a1668427cc0f upstream.
|
|
|
|
On some failures, the country_code field of an acm structure is freed
|
|
without freeing the acm structure itself. Elsewhere, operations including
|
|
memcpy and kfree are performed on the country_code field. The patch sets
|
|
the country_code field to NULL when it is freed, and likewise sets the
|
|
country_code_size field to 0.
