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

smb/client: fix out-of-bounds read in symlink data()

Since smb2 check message() returns success without length validation for the symlink error response, in symlink data() it is possible for iov->iov len to be smaller than sizeof(struct smb2 err rsp). If the buffer only contains the base SMB2 header (64 bytes), accessing err->ErrorContextCount (at offset 66) or err->ByteCount later in symlink data() will cause an out-of-bounds read.
