A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading to a kernel information leak.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
