What it is

In the Linux kernel, the following vulnerability has been resolved:

smb/client: fix possible infinite loop and oob read in symlink_data()

On 32-bit architectures, the infinite loop is as follows:

len = p->ErrorDataLength == 0xfffffff8

u8 *next = p->ErrorContextData + len

next == p

On 32-bit architectures, the out-of-bounds read is as follows:

len = p->ErrorDataLength == 0xfffffff0

u8 *next = p->ErrorContextData + len

next == (u8 *)p - 8
